Biblical Doctrine: An Overview

Updated: Jun 10


True Theology: Knowing and Loving God

The study of theology is considered by many to be dry, boring, irrelevant, and complicated. But for those who want to know God, the study of theology is indispensable. The word “theology” comes from two Greek words, theos (“God”) and logos (“word”). The study of theology is an effort to make definitive statements about God and his implications in an accurate, coherent, relevant way, based on God’s self-revelations. Doctrine equips people to fulfill their primary purpose, which is to glorify and delight in God through a deep personal knowledge of him. Meaningful relationship with God is dependent on correct knowledge of him.


Any theological system that distinguishes between “rational propositions about God” and “a personal relationship with God” fails to see this necessary connection between love and knowledge. The capacity to love, enjoy, and tell others about a person is increased by greater knowledge of that person. Love and knowledge go hand in hand. Good lovers are students of the beloved. Knowledge of God is the goal of theology.


Knowledge without devotion is cold, dead orthodoxy. Devotion without knowledge is irrational instability. But true knowledge of God includes understanding everything from his perspective. Theology is learning to think God’s thoughts after him. It is to learn what God loves and hates, and to see, hear, think, and act the way he does. Knowing how God thinks is the first step in becoming godly.


Many would like to think that just being a “good” person and “loving” God, without an emphasis on doctrine, is preferable. But being a good person can mean radically different things depending on what someone thinks “good” is, or what constitutes a “person.” Loving God will look very different depending on one’s conception of “God” or “love.” The fundamental connections between belief and behavior, and between love and knowledge, demand a rigorous pursuit of truth for those wanting to love God and to be godly. Hebrews 5:11–6:3 teaches that deepening theological understanding equips one to be able to differentiate good from evil, and it exhorts believers to mature in their knowledge of God and his ways:


For though by this time, you ought to be teachers, you need someone to teach you again the basic principles of the oracles of God. You need milk, not solid food, for everyone who lives on milk is unskilled in the word of righteousness, since he is a child. But solid food is for the mature, for those who have their powers of discernment trained by constant practice to distinguish good from evil. Therefore, let us leave the elementary doctrine of Christ and go on to maturity (Heb. 5:12–6:1).


Good theology is based in the belief that God exists, is personal, can be known, and has revealed himself. These presuppositions motivate theologians to devote themselves to a passionate pursuit of knowledge from God’s Word. Unfortunately, the word “theologian” is used almost exclusively for vocational theologians rather than for anyone earnestly devoted to knowing God. On one level everyone who thinks about God is a theologian. But a believer whose life is consumed with knowing his Lord is most certainly a theologian, and theologians are committed to truth.


Loving God means loving truth. God is a God of truth; he is truth. In Scripture, all three persons of the Trinity are vitally related to truth (see chart).


All Three Persons of the Trinity Vitally Related to Truth

Father

“What if some were unfaithful? Does their faithlessness nullify the faithfulness of God? By no means! Let God be true though every one were a liar, as it is written, ‘That you may be justified in your words, and prevail when you are judged’” (Rom. 3:3–4).

“For I tell you that Christ became a servant to the circumcised to show God’s truthfulness, in order to confirm the promises given to the patriarchs” (Rom. 15:8).


Son

“Jesus said to him, ‘I am the way, and the truth, and the life. No one comes to the Father except through me’” (John 14:6).

“But that is not the way you learned Christ!—assuming that you have heard about him and were taught in him, as the truth is in Jesus” (Eph. 4:20–21).


Spirit

“But when the Helper comes, whom I will send to you from the Father, the Spirit of truth, who proceeds from the Father, he will bear witness about me” (John 15:26).

“When the Spirit of truth comes, he will guide you into all the truth, for he will not speak on his own authority, but whatever he hears he will speak, and he will declare to you the things that are to come” (John 16:13).



In light of this relationship between God and truth, it should be no surprise that the Great Commandment includes loving God with one’s mind: “And you shall love the Lord your God with all your heart and with all your soul and with all your mind and with all your strength” (Mark 12:30, quoting Deut. 30:6). Fully loving God and obeying the Great Commandment requires actively engaging the mind in the pursuit of truth.


The second half of the Great Commandment—love your neighbor as yourself (Mark 12:31)—also requires a great commitment to truth. Love, kindness, and compassion must include profound concern that people understand the truth, since their lives depend on it. God meets man’s greatest need of relationship with him through an understanding of truth: “Of his own will [God] brought us forth by the word of truth, that we should be a kind of firstfruits of his creatures” (James 1:18; cf. 1 Pet. 1:23). Sanctification also happens by means of the truth: “Sanctify them in the truth; your word is truth” (John 17:17; cf. Rom. 12:2). Authentic discipleship is marked by knowing and obeying truth: “If you abide in my word, you are truly my disciples, and you will know the truth, and the truth will set you free” (John 8:31–32). Therefore, loving others involves having a deep desire that they understand truth. This is the reason the Great Commission has a vital teaching element. Making disciples of Christ involves teaching them to observe all he has commanded (Matt. 28:20). Jesus wants people to understand and obey truth and thereby find life in him. Failure to care whether or not loved ones understand the truth is failure to care about their abundant and eternal lives. People are judged and go to hell because they fail to love and obey God’s truth (2 Thess. 2:11–13; cf. Rom. 1:18, 21, 25; James 1:18; 1 Pet. 1:23).


Theological Method

Systematic theology seeks to summarize biblical teaching on particular topics in order to draw definitive conclusions that intersect with life. God has revealed himself to his people in human history, which is why he can be known personally. He has not only revealed himself in facts and statements, but what is objectively true of him has also been revealed in the subjective experience of historical events. The experiences God’s people had with him in the Bible become the basis for all believers experiencing him now.


God’s revelation in history is rich, personal, and wedded to real life. It can also be more difficult to understand than mere facts and propositions because the historical context of the revelation is often foreign to modern people. Because revelation of God is personal and historical, the biblical understanding of God is progressive and cumulative. The theologian then must consider the historical context and progressive nature of revelation at every stage. The theological process must include careful exegesis of passages that are relevant to the question being answered. Furthermore, exegesis should be done with great sensitivity to the historical context of the passages being studied. This theological method has produced several focused areas of study.


The Theological Process

The theological process can be categorized under several aspects and disciplines, as shown on the chart. In particular, systematic theology (the focus of these articles) builds on the conclusions of exegesis and biblical theology. It attempts to summarize the teaching of Scripture in a brief, understandable, and carefully formulated statement. It involves appropriately collecting, synthesizing, and understanding all the relevant passages in the Bible on various topics, and then summarizing their teachings clearly so that God’s people know what to believe and how to live in relation to theological questions.


The Theological Process

Exegesis

The process of seeking to determine the correct meaning out of a particular passage of Scripture.

Biblical theology

The study of scriptural revelation based on the historical framework presented in the Bible.

Systematic theology

A study that answers the question, “What does the whole Bible teach us today about a given topic?”

Historical theology

The study of how believers in different eras of the history of the church have understood various theological topics.

Philosophical theology

The study of theological topics primarily through the use of the tools and methods of philosophical reasoning and information gained from nature and reason (“general revelation”) apart from the Bible.

Practical theology

The study of how to best apply theological truths to the life of the church and the world (including preaching, Christian education, counseling, evangelism, missions, church administration, worship, etc.).

Apologetics

The study of theology for the purpose of defending Christian teaching against criticism and distortion, and giving evidences of its credibility.


Reference to this sort of whole-Bible theology can be seen in Paul’s insistence that he did not shrink back from declaring “the whole counsel of God” (Acts 20:27) and in Jesus’ Great Commission that the church should “make disciples of all nations” by “teaching them to observe all that I have commanded you” (Matt. 28:19–20).

Essential vs. Peripheral Doctrine

The ability to discern the relative importance of theological beliefs is vital for effective Christian life and ministry. Both the purity and unity of the church are at stake in this matter. The relative importance of theological issues can fall within four categories: (1) absolutes define the core beliefs of the Christian faith; (2) convictions, while not core beliefs, may have significant impact on the health and effectiveness of the church; (3) opinions are less-clear issues that generally are not worth dividing over; and (4) questions are currently unsettled issues. These categories can be best visualized as concentric circles, similar to those on a dart board, with the absolutes as the “bull’s-eye” (see diagram).



Where an issue falls within these categories should be determined by weighing the cumulative force of at least seven considerations: (1) biblical clarity; (2) relevance to the character of God; (3) relevance to the essence of the gospel; (4) biblical frequency and significance (how often in Scripture it is taught, and what weight Scripture places upon it); (5) effect on other doctrines; (6) consensus among Christians (past and present); and (7) effect on personal and church life. These criteria for determining the importance of particular beliefs must be considered in light of their cumulative weight regarding the doctrine being considered. For instance, just the fact that a doctrine may go against the general consensus among believers (see item 6) does not necessarily mean it is wrong, although that might add some weight to the argument against it. All the categories should be considered collectively in determining how important an issue is to the Christian faith. The ability to rightly discern the difference between core doctrines and legitimately disputable matters will keep the church from either compromising important truth or needlessly dividing over peripheral issues.


The Bible and Revelation

Knowing God is the most important thing in life. God created people fundamentally for relationship with himself. This relationship depends on knowing who he is as he has revealed himself. God is personal, which means he has a mind, will, emotions, relational ability, and self-consciousness. Because he is personal, and not merely an impersonal object, God must personally reveal himself to us. He has done this in general revelation (the world) and special revelation (the Word of God).


General Revelation

General revelation is revelation of God given to all people at all times. This revelation is found both in the external creation (Ps. 19:1, “the heavens declare the glory of God”) and in internal human experience (Rom. 1:19–20, “what can be known about God is plain to them, because God has shown it to them. For his invisible attributes, namely, his eternal power and divine nature, have been clearly perceived, ever since the creation of the world, in the things that have been made. So they are without excuse”). General revelation shows attributes of God—such as his existence, power, creativity, and wisdom; in addition, the testimony of human conscience also provides some evidence of God’s moral standards to all human beings (Rom. 2:14–15). This means that from general revelation all people have some knowledge that God exists, some knowledge of his character, and some knowledge of his moral standards. This results in an awareness of guilt before God as people instinctively know that they have not lived up to his moral requirements. Thus, in the many false religions that have been invented people attempt to assuage their sense of guilt.


But general revelation does not provide knowledge of the only true solution to man’s guilt before God: the forgiveness of sins that comes through Jesus Christ. This means that general revelation does not provide personal knowledge of God as a loving Father who redeems his people and establishes covenants with them. For this, one needs special revelation, which God has provided in his historical supernatural activities, in the Bible, and definitively in Jesus Christ.


Special Revelation

The Bible is God’s written revelation of who he is and what he has done in redemptive history. Humans need this divine, transcendent perspective in order to break out of their subjective, culturally bound, fallen limitations. Through God’s written Word, his people may overcome error, grow in sanctification, minister effectively to others, and live abundant lives as God intends.


The Inspiration of Scripture

The Bible is “God-breathed” (cf. 2 Tim. 3:16) and gets its true, authoritative, powerful, holy character from God himself, who inspired human authors to write exactly what he wanted them to write. Instead of merely dictating words to them, God worked through their unique personalities and circumstances. Scripture is therefore both fully human and fully divine. It is both the testimony of men to God’s revelation, and divine revelation itself. “No prophecy of Scripture comes from someone’s own interpretation. For no prophecy was ever produced by the will of man, but men spoke from God as they were carried along by the Holy Spirit” (2 Pet. 1:20–21). Because the Bible is God’s Word in human words, it can be trusted as the definitive revelation from the mouth of God himself.


The Inerrancy of Scripture

The doctrine of inerrancy means that the Bible is entirely truthful and reliable in all that it affirms in its original manuscripts. Another way of saying this is that the Bible does not affirm anything that is contrary to fact. Because God is the ultimate author of the Bible, and because God is always perfectly truthful, it follows that his Word is completely truthful as well: He is the “God who never lies” (Titus 1:2). It would be contrary to his character to affirm anything false. God is all-knowing, always truthful and good, and all-powerful, so he always knows and tells the truth and is able to communicate and preserve his Word. “O Lord GOD, you are God, and your words are true, and you have promised this good thing to your servant” (2 Sam. 7:28). “Every word of God proves true” (Prov. 30:5; cf. Ps. 12:6; 119:42; John 17:17).


Inerrancy does not require twenty-first-century precision or scientifically technical language. The following quotation from the Chicago Statement on Biblical Inerrancy summarizes what inerrancy does not mean:


We affirm the propriety of using inerrancy as a theological term with reference to the complete truthfulness of Scripture. We deny that it is proper to evaluate Scripture according to standards of truth and error that are alien to its usage or purpose. We further deny that inerrancy is negated by Biblical phenomena such as a lack of modern technical precision, irregularities of grammar or spelling, observational descriptions of nature, the reporting of falsehoods, the use of hyperbole and round numbers, the topical arrangement of material, variant selections of material in parallel accounts, or the use of free citations (Chicago Statement on Biblical Inerrancy, Art. XIII).


The inerrancy of Scripture gives the believer great confidence in the Bible as his sure foundation for understanding all God wants him to know and all that he needs for godliness and eternal life.


The Clarity of Scripture

The Bible itself acknowledges that some passages of Scripture are “hard to understand” (2 Pet. 3:16, referring to some aspects of Paul’s letters). In general, however, with the illumination of the Spirit (2 Tim. 2:7), the teaching of the Bible is clear to all who seek understanding with the goal of knowing and obeying God. OT believers were instructed to teach God’s commands continually to their children with the expectation that they would understand it: “These words that I command you today shall be on your heart. You shall teach them diligently to your children, and shall talk of them when you sit in your house, and when you walk by the way, and when you lie down, and when you rise” (Deut. 6:6–7). God’s Word is said to “make wise the simple” (Ps. 19:7; 119:30). Jesus based his teaching squarely on the OT Scriptures: he assumed its teaching was clear and would often ask, “Have you not read … ?” (cf. Matt. 12:3, 5; 19:14; 21:42; 22:31).


Because of the basic clarity of the Bible, when Christians disagree over the meaning of a passage they can assume that the problem is not with the Bible but rather with themselves as interpreters. Misunderstandings may be due to various factors such as human sin, ignorance of enough of the relevant data, faulty assumptions, or perhaps trying to reach a definite conclusion about a topic where the Bible has not given enough information to decide the question. Yet the emphasis of the Bible is not on difficulties in understanding but on the fact that ordinary believers are capable of comprehending Scripture for themselves. In addition, God provides teachers of his Word to further help his people’s understanding (1 Cor. 12:28; Eph. 4:11). Believers have the responsibility to read, interpret, and understand the Bible because it is basically clear. This was an assumption of the Protestant Reformers who sought to translate the Bible into the language of the common people. They believed that all true Christians are priests who are able to know God for themselves through his Word and to help others do the same.


The Sufficiency of Scripture

Scripture provides all the words from God that we need in order to know God truly and personally, and everything we need him to tell us in order for us to live an abundant, godly life (Ps. 19:7–9; 2 Tim. 3:15). God has given his people a sufficient revelation of himself so that they are able to know, trust, and obey him. “All Scripture is breathed out by God and profitable for teaching, for reproof, for correction, and for training in righteousness, that the man of God may be competent, equipped for every good work” (2 Tim. 3:16–17). God commands that nothing be added or taken away from the Bible, which indicates that it has always been exactly what he has wanted at each stage in its development throughout the history of salvation. “You shall not add to the word that I command you, nor take from it, that you may keep the commandments of the LORD your God that I command you” (Deut. 4:2; cf. Deut. 12:32; Prov. 30:5–6). The powerful admonition against tampering that stands at the conclusion of the entire Bible (Rev. 22:18–19) applies primarily, of course, to the book of Revelation, but in a secondary sense what it says may be applied to the Bible as a whole: “I warn everyone who hears the words of the prophecy of this book: if anyone adds to them, God will add to him the plagues described in this book, and if anyone takes away from the words of the book of this prophecy, God will take away his share in the tree of life and in the holy city, which are described in this book” (Rev. 22:18–19).


Believers should find freedom and encouragement in the knowledge that God has provided all of the absolutely authoritative instruction that they need in order to know him and live as he intends. God’s people should never fear that he has withheld something they might need him to say in order for them to know how to please him, or that he will have to somehow supplement his Word with new instructions for some new situation that arises in the modern age. (The NT allows for the activity of the Holy Spirit in leading and guiding individuals, as in Rom. 8:14; Gal. 5:16, 18, 25; but this guidance is always in line with Scripture, never in opposition to scriptural commands.) Therefore believers should be satisfied with what Scripture teaches and what it leaves unsaid. “The secret things belong to the LORD our God, but the things that are revealed belong to us and to our children forever, that we may do all the words of this law” (Deut. 29:29).


Jesus’ View of Scripture

The most convincing reason to believe that the Bible is inspired, inerrant, clear, and sufficient is because this is what Jesus believed. His teaching assumed that the OT was the authoritative Word of his Father: “Do not think that I have come to abolish the Law or the Prophets; I have not come to abolish them but to fulfill them. For truly, I say to you, until heaven and earth pass away, not an iota, not a dot, will pass from the Law until all is accomplished” (Matt. 5:17–18). Jesus referred to dozens of OT persons and events and always treated OT history as historically accurate. He quoted from Genesis as his Father’s Word when he said, “Have you not read that he who created them from the beginning made them male and female, and said, ‘Therefore a man shall leave his father and his mother and hold fast to his wife, and the two shall become one flesh’? So they are no longer two but one flesh. What therefore God has joined together, let not man separate” (Matt. 19:4–6). Jesus not only assumed that the creation story was true, he also freely quoted words from the OT narrator as words that God himself “said.” It is not uncommon for Jesus’ theological arguments to depend on the truthfulness of the OT account (Matt. 5:12; 11:23–24; 12:41–42; 24:37–39; Luke 4:25–27; 11:50–51; John 8:56–58). Jesus’ view of the OT as the Word of God aligns with the way the OT regularly speaks of itself.


Jesus saw his entire life as a fulfillment of Scripture (Matt. 26:54; Mark 8:31). Throughout his life, Jesus used Scripture to resist temptation (Matt. 4:1–11) and to settle disputes (Matt. 19:1–12; 22:39; 27:46; Mark 7:1–13; Luke 10:25–26). At the end of his life, Jesus died quoting Scripture (cf. Matt. 27:46 with Ps. 22:1). On his resurrection day he explained Scripture at length on the Emmaus road and to his disciples in Jerusalem (Luke 24:13–17, 44–47).


Conscious of his identity as God the Son, Jesus saw his teaching as no less divinely inspired than the OT. Jesus taught with an authority that distinguished him from other teachers of the law. He interpreted the law on his own authority rather than depending on rabbinic sources (Matt. 5:21–48). He described his teaching and the law as sharing the same permanence: “heaven and earth will pass away, but my words will not pass away” (Matt. 24:35, cf. Matt. 5:17–18; John 14:10, 24). Jesus viewed both the OT and his own teaching as the Word of God. The NT apostolic witness was a result of Jesus giving his disciples authority and power through the Holy Spirit to impart spiritual truths in writing no less than by word of mouth (Mark 3:13–19; John 16:12–14; Acts 26:16–18; 1 Cor. 2:12–13).


Jesus took Scripture to be the authoritative Word of God upon which he based his entire life. Those who follow Christ are called to treat Scripture (OT and NT together) in the same way. For Christians, the Bible is a source of great delight and joy. God is to be diligently sought in his Word (1 Pet. 2:2). The Word of God is a precious treasure that deserves to be studied, meditated upon, and obeyed:


My son, if you receive my words and treasure up my commandments with you, making your ear attentive to wisdom and inclining your heart to understanding; yes, if you call out for insight and raise your voice for understanding, if you seek it like silver and search for it as for hidden treasures, then you will understand the fear of the LORD and find the knowledge of God (Prov. 2:1–5).


What It Means to Know God

In the quest to know God, it is vital to understand just what it means to really know him. Methods, expectations, and attitudes in studying theology are determined by one’s definition of “knowing God.” Central to understanding this is the fact that God is both incomprehensible and knowable.


The Incomprehensibility of God

Scripture teaches that we can have a true and personal knowledge of God, but this does not mean we will ever understand him exhaustively. The Bible is clear that God is ultimately incomprehensible to us; that is, we can never fully comprehend his whole being. The following passages show this:


Great is the LORD, and greatly to be praised, and his greatness is unsearchable (Ps. 145:3).“Behold, these are but the outskirts of his ways, and how small a whisper do we hear of him! But the thunder of his power who can understand?” (Job 26:14).“For my thoughts are not your thoughts, neither are your ways my ways, declares the LORD. For as the heavens are higher than the earth, so are my ways higher than your ways and my thoughts than your thoughts” (Isa. 55:8–9).Oh, the depth of the riches and wisdom and knowledge of God! How unsearchable are his judgments and how inscrutable his ways! “For who has known the mind of the Lord, or who has been his counselor?” (Rom. 11:33–34; cf. Job 42:1–6; Ps. 139:6, 17–18; 147:5; Isa. 57:15; 1 Cor. 2:10–11; 1 Tim. 6:13–16).


These verses teach that not only is God’s whole being incomprehensible but each of his attributes—his greatness, power, thoughts, ways, wisdom, and judgments—are well beyond human ability to fathom fully. Not only can we never know everything there is to know about God, we can never know everything there is to know about even one aspect of God’s character or work.


Why God Is Incomprehensible

The main reasons for God’s incomprehensibility are: (1) God is infinite, and his creatures are finite. By definition, creatures depend on their Creator for their very existence and are limited in all aspects. Yet God is without limitations in every quality he possesses. This Creator/creature, infinite/finite gap will always exist. (2) The perfect unity of God’s attributes is far beyond the realm of human experience. God’s love, wrath, grace, justice, holiness, patience, and jealousy are continually functioning in a perfectly integrated yet infinitely complex way. (3) The effects of sin on the minds of fallen humans also greatly inhibit the ability to know God. The tendency of fallen creatures is to distort, pervert, and confuse truth and to use, or rather abuse, it for selfish ends rather than for God’s glory (Rom. 1:18–26). (4) A final reason God can never be fully known is that in his sovereign wisdom God has chosen not to reveal some things: “The secret things belong to the LORD our God, but the things that are revealed belong to us and to our children forever, that we may do all the words of this law” (Deut. 29:29). Many would label it unloving for God to decide to withhold some information from his people. They wrongly believe God should reveal everything they may want to know. Yet, as with all good fathers, God’s wisdom leads him to refrain from answering all the questions his children ask him, and this contributes to his incomprehensibility.


In heaven, God’s incomprehensibility will no doubt be lessened when the effects of sin no longer ravage minds and when he will most likely share some of his secrets. However, God will always be infinite and humans will always be finite, so he will always be beyond human ability to know exhaustively.


Implications of God’s Incomprehensibility

Because God can never be fully known, those who seek to know God should be deeply humbled in the process, realizing that they will always have more to learn. The appropriate response to God is a heart of wonder and awe in light of his incomprehensible greatness. God’s incomprehensibility also means that beliefs can be held with firm conviction even though they may be filled with inexplicable mystery. The Trinity, the divine and human natures of Christ, divine sovereignty and human responsibility, and many other core teachings of the Christian faith are profoundly mysterious; believing them requires a robust affirmation of the incomprehensibility of God.


The Knowability of God

The incomprehensibility of God could lead to despair or apathy in the quest to know God, but the Bible also teaches that God is knowable. While God can never be exhaustively understood, he can be known truly, personally, and sufficiently. God is personal, has definite characteristics, and has personally revealed himself so that he can be truly known. The multiplication of grace and peace in our lives is dependent on knowing God (2 Pet. 1:2–3), and this knowledge provides sufficient resources for life and for becoming the people God wants us to be.


Knowledge of God in Christ should be our greatest delight (Jer. 9:23–24; 1 Cor. 2:2; Gal. 6:14). It is the basis of attaining eternal life (John 17:3); it is at the heart of life in the new covenant (Heb. 8:11–12); it was Paul’s primary goal (Phil. 3:10); and it leads to godly love (1 John 4:7–8). God will never be known absolutely, but we can know things about him that are absolutely true, so much so that we can be willing to live and die for those beliefs. God has provided knowledge of himself that is personal, relational, and sufficient for fruitful, faithful, godly living. No one will ever be able to say he lacked the necessary revelation to know God and to start living as God intends.

Implications of the Knowability of God


God’s personal and sufficient revelation of himself should foster solid conviction among believers. We need not live in ambiguity and uncertainty about who God is and what he demands of his creatures. The increasing influence of Eastern religions on the West, certain postmodern views of truth, and religious pluralism all emphasize God’s incomprehensibility so much that he is eventually made to seem unknowable. It then becomes impossible to say anything definitively true or false about him, and people then think that the only heresy is claiming that there is any heresy at all! On the contrary, because of his gracious revelation and illumination, God can indeed be known. God’s knowability should lead to eager, diligent, devoted study of God’s Word so that we can understand him as he has revealed himself and avoid any false view of God that will dishonor him. We should never grow apathetic in seeking to know God because we are in fact able and equipped to know him and to please him with our lives.


The Character of God

“Without faith it is impossible to please [God]” (Heb. 11:6)—but it is also impossible to have faith in God without knowing the character of God. Faith is belief in God’s promises, which in turn are grounded in his character.


Ways in Which God Reveals Himself

God has revealed himself primarily in four overlapping ways: (1) actions; (2) names; (3) images; and (4) attributes, as seen in the chart. God reveals himself through actions, names, and images because they carry vivid, experiential, creative, and situational power. However, it is God’s attributes that are the fundamental descriptions of who he is.


Means of Revelation

Examples

actions

creating, judging, redeeming

names

“LORD” (Hb. YHWH, or Yahweh)


“God Almighty” (Hb. el Shadday)


“Master, Lord” (Hb. ‘Adon)

images

Father, Rock, Husband, Shepherd

attributes

holiness, goodness, love, grace, wrath


Actions of God

God shows who he is in what he does. In creating the world, God shows his power, wisdom, beauty, goodness, and prodigious creativity. After the creation of humanity God talks to, walks with, and seeks out humans, even when they lapse into rebellion against him, showing that he is relational, personal, engaged, and caring. God demonstrates his holiness, wrath, and justice when he curses human rebellion in the garden and judges the unrighteous through the flood in Noah’s day. He shows his grace and mercy in establishing a covenant with Noah and Abraham. In sending his Son to live and die for humanity, he shows amazing love and compassion. Whenever God acts, we see his character displayed.


Names of God

God offers his name as a personal introduction and as a window into his character. This is why David says, “Those who know your name put their trust in you” (Ps. 9:10). To know his name is to know he is trustworthy. God’s act of naming himself is a profoundly gracious act of accommodation and engagement.


Among the many names for God in the Bible, there is none more important than Yahweh (translated “LORD”), a name that was revealed to Moses at the burning bush (Ex. 3:15). Linguistically related to the verb “I am,” Yahweh is packed with theological import. It most likely communicates God’s self-existence, independence, self-sufficiency, eternality, and unchanging character. These transcendent qualities are powerfully complemented when God also tells Moses to refer to him as “the God of your fathers” (Ex. 3:15). God is both majestic and intimate, the great, eternal “I AM,” the God who knows his children by name and keeps his covenant promises. Christian worship, discipleship, and preaching must maintain both healthy fear of the Lord and freedom and confidence in his presence.


Another striking and revealing name for God is “Jealous” (Hb. ’El qana’). God tells Moses that he is so jealous for his glory expressed in the faithfulness of his people that “Jealous” is an appropriate name for himself. The reason God gives for his commandment against idolatry is grounded in his character as a jealous God: “For you shall worship no other god, for the LORD, whose name is Jealous, is a jealous God” (Ex. 34:14). God deserves and demands absolute, exclusive loyalty and hates spiritual adultery. In his jealous love he refuses to allow his people to be supremely devoted to anything but himself. Because he is absolutely worthy of worship, allowing his people to love anything more than him would compromise his justice and love.


Images of God

Images of God are analogies from daily life that serve to illustrate his attributes. Among many other images, God is: Father, King, Consuming Fire, Judge, Husband, Shepherd, Potter, Farmer, Refiner, Landowner, Lion, Bear, Light, Water, Tower, and Lamb! These amazingly diverse descriptions from a multitude of human experiences offer pictures of God that reach minds and hearts in ways that abstract definitions do not. Images, like attributes and names, must be considered in relation to one another. If certain images are emphasized at the expense of others, God’s character will be misunderstood. The varied images in the Bible are all complementary to each other, and each is vital for understanding God. For example, God as the Rock points out his strength, stability, and justice, while God as Husband gives insight into his loving, faithful, committed heart for his covenant people.


The image of God as a Rock is used in both OT and NT. Deuteronomy 32 especially highlights God as Rock in light of Israel’s unfaithfulness: “You were unmindful of the Rock that bore you, and you forgot the God who gave you birth” (Deut. 32:18; cf. Deut. 32:4, 13, 15, 30, 31, 37). Paul uses this image as a title of strength and applies it to Christ in 1 Corinthians 10:4: “and all drank the same spiritual drink. For they drank from the spiritual Rock that followed them, and the Rock was Christ.” Although the Rock (Hb. tsur) of Deuteronomy 32 is Yahweh, Paul applies the same title to Jesus. The Rock that followed and provided for the Israelites in the wilderness in the old covenant was the Christ who provides for the Corinthian believers in the new covenant. The Rock in the wilderness shares the same attributes as the Rock of the table, cup, and bread.


The strength and stability of the rock imagery is beautifully complemented by the tender, compassionate image of God as the Husband of his people. “For your Maker is your husband, the LORD of hosts is his name; and the Holy One of Israel is your Redeemer, the God of the whole earth he is called” (Isa. 54:5; cf. Jer. 2:2; Hosea 1–3). God’s relational involvement with his people is so intimate and personal that he is jealous when his people are unfaithful. God speaks with the jealous voice of a husband who has been betrayed by an adulterous wife: “Surely, as a treacherous wife leaves her husband, so have you been treacherous to me, O house of Israel, declares the LORD” (Jer. 3:20). The idea of God as a rock could lead to impersonal, static, cold conceptions, were it not for the intensely loving, engaged husband imagery. The marriage metaphor could reduce God to being weak, vulnerable, and pathetic if not for images like a rock (and a king, warrior, fire, etc.). Images of God bring his attributes from being mere abstractions into vivid clarity because they are based on our experiences of life.


Attributes of God

The attributes of God are the normative descriptions that images, names, and actions illuminate from different perspectives. His attributes are his essential characteristics that make him who he is. God’s attributes are typically classified as either incommunicable or communicable. Incommunicable attributes are not shared by humans as are communicable attributes. The attributes can be organized using the classifications shown in Incommunicable Attributes and Communicable Attributes.

Incommunicable Attributes

Independence (self-existence, self-sufficiency, aseity)

Unchangeableness (immutability)

Eternity

Omnipresence

Unity (simplicity)

The Unity of God

This list of classified attributes of God can be helpful in developing an organized perspective on God’s character. However, his character cannot be reduced to a quantifiable list of properties. Maintaining the unity of God’s attributes is essential in the study of his character. His unity means that although we experience certain attributes more clearly at certain times, nevertheless, his attributes are not divided into parts and must always be understood interdependently. His attributes are not petals on a flower to be plucked off and viewed in isolation from the rest. The unity of God requires finite creatures to pursue a holistic understanding of him. When God expresses judgment and wrath, he does not cease to be merciful, patient, or kind in that moment. He never expresses certain attributes at the expense of others. Fallen humans tend to emphasize attributes that affirm our personal inclinations, experience, and contemporary sensibilities. Considering God’s attributes independently of each other leads to unbalanced idolatrous conceptions of God. A biblically integrated understanding of God involves, along with a list of attributes, the work of the Spirit, the whole counsel of God’s Word accurately interpreted, the input of church history, and the input of believers from diverse cultures.


Examples of Application to Life

The two charts labeled “Practical Implications” offer a brief survey of some of God’s attributes. Each section of the charts provides a basic definition of an attribute (based on Wayne Grudem’s Systematic Theology), a key passage of supporting Scripture, and one basic implication for daily life.


Practical Implications of the Incommunicable Attributes of God

Attribute

Scripture

Implication

Independence: God does not need us or the rest of creation for anything, yet we and the rest of creation can glorify him and bring him joy.

“The God who made the world and everything in it, being Lord of heaven and earth, does not live in temples made by man, nor is he served by human hands, as though he needed anything, since he himself gives to all mankind life and breath and everything” (Acts 17:24–25; cf. Ex. 3:14; Job 41:11; Ps. 50:9–12; 90:2).

God never experiences need, so serving God should never be motivated by the thought that he needs us. He is the provider in everything.

Immutability: God is unchanging in his being, perfections, purposes, and promises, although as he acts in response to different situations he feels emotions.

“For I the LORD do not change; therefore you, O children of Jacob, are not consumed” (Mal. 3:6; for “being,” cf. Ps. 102:25–27; Mal. 3:6; James 1:17; for “purposes,” cf. Ps. 33:11; Isa. 46:9–11; for “promises,” cf. Num. 23:19; Rom. 11:29).

God can always be trusted because he always keeps his word, and is never capricious or moody.

Eternity: God has no beginning or end and is in no way bound by time, although he sees events and acts in his world in time, which is in fact one dimension of the created order.

“Before the mountains were brought forth, or ever you had formed the earth and the world, from everlasting to everlasting you are God” (Ps. 90:2; cf. Ex. 3:14; Job 36:26; Ps. 90:4; Isa. 46:9–10; John 8:58; 1 Tim. 6:16; 2 Pet. 3:8; Jude 24–25; Rev. 1:8; 4:8).

Those who trust the God of eternity can know peace, rest, and comfort in the busyness of life and in spite of impending death, for God keeps them in safety and joy forever.

Omnipresence: God does not have spatial dimensions and is present everywhere with his whole being, though he acts differently in different situations.

“Am I a God at hand, declares the LORD, and not a God far away? Can a man hide himself in secret places so that I cannot see him? declares the LORD. Do I not fill heaven and earth?” (Jer. 23:23–24; cf. 1 Kings 8:27; Ps. 139:7–10; Isa. 66:1–2; Acts 7:48–50).

God can be sought anywhere regardless of place. Believers should never feel lonely, and the wicked should never feel safe.

Practical Implications of the Communicable Attributes of God

Attribute

Scripture

Implication

Holiness: God is absolutely and uniquely excellent above all creation (majesty) and without sin (purity).

“And the four living creatures, each of them with six wings, are full of eyes all around and within, and day and night they never cease to say, ‘Holy, holy, holy, is the Lord God Almighty, who was and is and is to come!’” (Rev. 4:8; for “majestic holiness,” cf. Ex. 15:11; 1 Chron. 16:27–29; Isa. 57:15; for “moral holiness,” cf. Isa. 5:16; 6:1–8; Acts 3:14; Heb. 7:26).

God should be feared and obeyed, and his people should earnestly pursue moral purity.

Omnipotence: God is able to do all his holy will.

“Remember the former things of old; for I am God, and there is no other; I am God, and there is none like me, declaring the end from the beginning and from ancient times things not yet done, saying, ‘My counsel shall stand, and I will accomplish all my purpose’” (Isa. 46:9–10; cf. Ex. 6:3; Job 37:23; 40:2; 42:1–6; Ps. 24:6; 33:10–11; 91:1; Dan. 4:34–35; Matt. 28:18).

God’s ultimate will is never frustrated by evil, so there is peace and confidence in the face of suffering for those who trust God.

Sovereignty: God has absolute rule over creation as King and total control and determination over all that happens.

“His dominion is an everlasting dominion, and his kingdom endures from generation to generation; all the inhabitants of the earth are accounted as nothing, and he does according to his will among the host of heaven and among the inhabitants of the earth; and none can stay his hand or say to him, ‘What have you done?’” (Dan. 4:34–35; cf. 1 Chron. 29:11–13; Ps. 22:28; 24:1; 47:7–9; 103:19; Prov. 16:19, 21, 33; Dan. 4:25; 7:1–28; 12:1–13; Matt. 6:13; 10:29; Acts 17:26; Eph. 1:11; 1 Tim. 6:15; James 1:13–15).

Mankind should obey and submit to God as humble subjects of his kingdom.

Omniscience: God fully knows himself and all things actual and possible—past, present, and future.

“Whenever our heart condemns us, God is greater than our heart, and he knows everything” (1 John 3:20; cf. Job 28:24; 37:16; Ps. 139:1–3; 147:5; Isa. 55:8–9; Matt. 10:29–30; Rom. 11:33–34; 1 Cor. 2:10–11; Heb. 4:13).

All God’s thoughts and actions are perfectly informed by perfect knowledge, so he is perfectly trustworthy.

Wisdom: God always knows and chooses the best goals and the best means to those goals. Wisdom is a moral as well as an intellectual quality.

“Blessed be the name of God forever and ever, to whom belong wisdom and might” (Dan. 2:20; cf. Job 9:4; 12:13; Ps. 104:24; Rom. 11:33; 16:27; 1 Cor. 1:21–29; Eph. 3:10–11).

God’s wisdom is not always clear to us, but it is great, deep, valuable, and should be highly desired and sought, and we should not doubt its reality even in circumstances that upset us.

Love: God freely and eternally gives of himself. The ultimate historical demonstration of God’s love is seen in the cross of Christ.

“Anyone who does not love does not know God, because God is love. In this the love of God was made manifest among us, that God sent his only Son into the world, so that we might live through him. In this is love, not that we have loved God but that he loved us and sent his Son to be the propitiation for our sins” (1 John 4:8–10; cf. John 3:16; 15:13; 17:24; Rom. 5:8; 8:31–39; Gal. 2:20; 1 John 3:16; 4:16).

God is eager to extravagantly give of himself to meet the needs of lost sinners, so they should flee to him with confidence (cf. Rom. 8:32).

Wrath: God intensely hates and responds with anger to all sin and rebellion. God hates every threat to what he loves.

“Then the kings of the earth and the great ones and the generals and the rich and the powerful, and everyone, slave and free, hid themselves in the caves and among the rocks of the mountains, calling to the mountains and rocks, ‘Fall on us and hide us from the face of him who is seated on the throne, and from the wrath of the Lamb’” (Rev. 6:15–16; cf. Ex. 34:7; Rom. 1:18; 2:4; 2 Cor. 5:10; 2 Thess. 1:5; 2 Pet. 3:9).

God should be greatly feared. Unbelievers should fear his judgment and turn to Christ for salvation. Believers should fear God’s fatherly discipline. The God who loves us is also the holy God who hates sin (1 Pet. 1:17).


God’s Attributes Are Seen Most Clearly in Christ

Jesus Christ is the most definitive revelation of all of these attributes. To see God’s character we look ultimately to God incarnate: “For God, who said, ‘Let light shine out of darkness,’ has shone in our hearts to give the light of the knowledge of the glory of God in the face of Jesus Christ” (2 Cor. 4:6). In the cross of Christ all God’s major attributes are displayed in condensed lucidity. His wrath, grace, justice, mercy, sovereignty, goodness, love, holiness, compassion, wisdom, and power meet there for the world to see. When discussions of God’s attributes become esoteric and sterile, it is the face and cross of Christ that restores radical clarity, reality, and compelling beauty.


The Trinity

The biblical teaching on the Trinity embodies four essential affirmations:


  1. There is one and only one true and living God.

  2. This one God eternally exists in three persons—God the Father, God the Son, and God the Holy Spirit.

  3. These three persons are completely equal in attributes, each with the same divine nature.

  4. While each person is fully and completely God, the persons are not identical.


The differences among Father, Son, and Holy Spirit are found in the way they relate to one another and the role each plays in accomplishing their unified purpose.


The unity of nature and distinction of persons of the Trinity is helpfully illustrated in the diagram.




God Is One God: Monotheism

There is nothing more fundamental to biblical theology than monotheism (the biblical belief that there is one and only one God): “Hear, O Israel: the LORD our God, the LORD is one” (Deut. 6:4). This verse, known as the Shema in Hebrew (from the opening verb of the verse, meaning “hear” or “listen”), is one of the most familiar and foundational verses in the OT. God rejects polytheism (belief in many gods) and demands exclusive devotion: “I am the LORD, and there is no other, besides me there is no God” (Isa. 45:5; cf. Deut. 4:35, 39; 1 Kings 8:60; Isa. 40:18; 46:9). The NT affirms the deity of the Father, Son, and Holy Spirit, as we shall see, but does not waver from OT monotheism (John 17:3; 1 Cor. 8:4–6; 1 Tim. 2:5; James 2:19). Jesus quotes the Shema in a debate with the Jewish leaders (Mark 12:29), and Paul continues to teach that there is one God while recognizing Jesus as the divine-human Mediator between God and man (1 Tim. 2:5).


Implications of Monotheism

Because there is only one God, idolatry of any kind is evil, foolish, wrong, and harmful. Worship of other “gods” robs the true God of the devotion and glory he alone deserves. Idolatry can take many forms. Idols are not only man-made objects but are anything allowed to compete with God for ultimate loyalty. According to Jesus, money can become an idol: “You cannot serve God and money” (Matt. 6:24). Greed, lust, and impurity can also become indicators of idolatry (Eph. 5:5; Col. 3:5). Idolatry is foolish, deceptive, and dangerous—and may even involve demonic activity (1 Cor. 10:19–20).


Because there is only one God, he alone should be the ultimate object of the believer’s affections. He alone deserves absolute allegiance and obedience. The Great Commandment that follows the Shema is the obvious implication of monotheism: “You shall love the LORD your God with all your heart and with all your soul and with all your might” (Deut. 6:5). The one true God deserves all we are and have. He deserves wholehearted love because nothing compares with him.


God Is Three Persons: The Tri-unity of God

As the nature of God is progressively revealed in Scripture, the one God is seen to exist eternally in three persons. These three persons share the same divine nature yet are different in role and relationship. The basic principle at the heart of God’s triune being is unity and distinction, both coexisting without either being compromised. Anything that is necessarily true of God is true of Father, Son, and Spirit. They are equal in essence yet distinct in function.


The doctrine of the Trinity is most fully realized in the NT where the divine Father, Son, and Spirit are seen accomplishing redemption. But while the NT gives the clearest picture of the Trinity, there are hints within the OT of what is yet to come. In the beginning of the Bible, the Spirit of God is “hovering over the face of the waters” at creation (Gen. 1:2) and is elsewhere described as a personal being, possessing the attributes of God and yet distinct from Yahweh (Isa. 48:16; 61:1; 63:10). Some interpreters think that the plurality within God is seen in the Hebrew word for God, ’Elohim, which is plural in form (though others disagree that this is significant; the word is used with singular verbs and all agree that it has a singular meaning in the OT). In addition, the use of plural pronouns when God refers to himself hints at a plurality of persons: “Then God said, ‘Let us make man in our image’” (Gen. 1:27; cf. Gen. 3:22; 11:7; Isa. 6:8). The plurality of God also seems to be indicated when the Angel of the Lord appears in the OT as one who represents Yahweh, while yet at times this angel seems to be no different in attributes or actions from God himself (cf. Gen. 16:7, 10–11, 13; 18:1–33; Ex. 3:1–4:31; 32:20–22; Num. 22:35, 38; Judg. 2:1–2; 6:11–18). There are also passages in the OT that call two persons God or Lord: “Your throne, O God, is forever and ever. The scepter of your kingdom is a scepter of uprightness; you have loved righteousness and hated wickedness. Therefore God, your God, has anointed you with the oil of gladness above your companions” (Ps. 45:6–7). David says, “The LORD says to my Lord: ‘Sit at my right hand, until I make your enemies your footstool’” (Ps. 110:1). The God who is set above his companions (Ps. 45:6) and the Lord of Psalm 110:1 are recognized as Christ in the NT (Heb. 1:8, 13). Christ himself applies Psalm 110:1 to himself (Matt. 22:41–46). Other passages give divine status to a messianic figure distinct from Yahweh (Prov. 8:22–31; 30:4; Dan. 7:13–14).


The OT glimpses of God’s plurality blossom into the full picture of the Trinity in the NT, where the deity and distinct personalities of Father, Son, and Spirit function together in perfect unity and equality (on the deity of Christ and the Holy Spirit, see The Person of Christ). Perhaps the clearest picture of this distinction and unity is Jesus’ baptism, where the Son is anointed for his public ministry by the Spirit, descending as a dove, with the Father declaring from heaven, “This is my beloved Son, with whom I am well pleased” (Matt. 3:13–17). All three persons of the Trinity are present, and each one is doing something different.


The NT authors employ a Trinitarian cadence as they write about the work of God. Prayers of blessing and descriptions of gifts within the body of Christ are Trinitarian in nature: “The grace of the Lord Jesus Christ and the love of God and the fellowship of the Holy Spirit be with you all” (2 Cor. 13:14); “Now there are varieties of gifts, but the same Spirit; and there are varieties of service, but the same Lord; and there are varieties of activities, but it is the same God who empowers them all in everyone” (1 Cor. 12:4–6). The persons of the Trinity are also linked in the baptismal formula of Matthew 28:19–20, “baptizing them in [or into] the name of the Father and of the Son and of the Holy Spirit.” There are many other passages that reveal the Trinitarian, or at least the plural, nature of God (e.g., John 14:16, 26; 16:13–15; 20:21–22; Rom. 8:9; 15:16, 30; 2 Cor. 1:21–22; Gal. 4:4–6; Eph. 2:18; 4:4–6; 1 Pet. 1:1–2; 1 John 4:2, 13–14; Jude 20–21).


Differences in roles also appear consistently in biblical testimonies concerning the relationships between the Father, Son, and Holy Spirit. The uniform pattern of Scripture is that the Father plans, directs, and sends; the Son is sent by the Father and is subject to the Father’s authority and obedient to the Father’s will; and both Father and Son direct and send the Spirit, who carries out the will of both. Yet this is somehow consistent with equality in being and in attributes. The Father created through the Son (John 1:3; 1 Cor. 8:6; Col. 1:16; Heb. 1:2), and the Father planned redemption and sent the Son into the world (John 3:16; Rom. 8:29; Gal. 4:4; Eph. 1:3–5). The Son obeyed the Father and accomplished redemption for us (John 4:34; 5:19; 6:38; Heb. 10:5–7; cf. Matt. 26:64; Acts 2:33; 1 Cor. 15:28; Heb. 1:3). The Father did not come to die for our sins, nor did the Holy Spirit, but that was the role of the Son. The Father and Son both send the Holy Spirit in a new way after Pentecost (John 14:26; 15:26; 16:7). These relationships existed eternally (Rom. 8:29; Eph. 1:4; Rev. 13:8), and they provide the basis for simultaneous equality and differences in various human relationships.


Within God there is both unity and diversity: unity without uniformity, and diversity without division. The early church saw this Trinitarian balance clearly. For example, the Athanasian Creed (c. A.D. 500) says:

We worship one God in the Trinity and the Trinity in unity; we distinguish among the persons, but we do not divide the substance. … The entire three persons are co-eternal and co-equal with one another, so that … we worship complete unity in Trinity and Trinity in Unity.

This unity and diversity is at the heart of the great mystery of the Trinity. Unity without uniformity is baffling to finite minds, but the world shows different types of reflections of this principle of oneness and distinction at every turn. What is the source of the transcendent beauty in a symphony, the human body, marriage, ecosystems, the church, the human race, a delicious meal, or a perfectly executed fast break in basketball? Is it not, in large part, due to the distinct parts coming together to form a unified whole, leading to a unified result? Unity and distinction—the principle at the heart of the Trinity—can be seen in much of what makes life so rich and beautiful. Woven into the fabric of the world are multiple reflections of the One who made it with unity and distinction as the parallel qualities of its existence.


Historical Misunderstandings of the Trinity

One of the most fundamental ways to misunderstand the Trinity is tritheism, which overemphasizes the distinction between the persons of the Trinity and ends up with three gods. This view neglects the oneness of the natures of Father, Son, and Holy Spirit. At the other end of the spectrum is the heresy of modalism (also known as Sabellianism, named after its earliest proponent, Sabellius, 3rd century), which loses the distinctions between the persons and claims that God is only one person. In this view, the appearance of the three persons is merely three modes of existence of the one God. For instance, God reveals himself as Father when he is creating and giving the law, as Son in redemption, and as Spirit in the church age. A contemporary version of modalism is found in the teaching of Oneness Pentecostalism. Both tritheism and modalism fail to maintain the biblical balance between the one reality of God and his eternal existence in three persons. A third error is to deny the full deity of the Son and of the Holy Spirit, and to say that they were at some time created. This is the heresy of Arianism (after a teacher named Arius, c. A.D. 256–336), and it is held today by Jehovah’s Witnesses.


Practical Implications of the Trinity

What are some of the practical implications of the doctrine of the Trinity?


1. The doctrine of the Trinity makes definitive revelation of God possible as he is known in Christ: “No one has ever seen God; the only God, who is at the Father’s side, he has made him known” (John 1:18). No man can see God and live (Ex. 33:20; 1 Tim. 6:16), but God the Son provided an actual manifestation of God in the flesh.


2. The Trinity makes the atonement possible. Redemption of sinful man is accomplished through the distinct and unified activity of each person of the Godhead: “how much more will the blood of Christ, who through the eternal Spirit offered himself without blemish to God, purify our conscience from dead works to serve the living God” (Heb. 9:14).


3. Because God is triune, he has eternally been personal and relational in his own being, in full independence from his creation. God has never had any unmet needs, “nor is he served by human hands, as though he needed anything, since he himself gives to all mankind life and breath and everything” (Acts 17:25). Personhood becomes real only within realized relationships, and the reality of relationship can only exist where one has something or someone that is not oneself to relate to; if, then, God had not been plural in himself he could not have been a personal, relational God till he had begun creating, and thus would have been dependent on creation for his own personhood, which is a notion as nonsensical as it is unscriptural. Between the persons of the Trinity, there has always existed total relational harmony and expression; God is, from this standpoint, a perfect society in himself. Apart from the plurality in the Trinity, either God’s eternal independence of the created order or his eternally relational personal existence would have to be denied.


4. The Trinity provides the ultimate model for relationships within the body of Christ and marriage (1 Cor. 11:3; 12:4–6; Eph. 4:4–7).


The doctrine of the Trinity is well beyond human ability to ever fully comprehend. However, it is central to understanding the nature of God and the central events in the history of salvation, in which God is seen acting as, in effect, a tripersonal team. Biblical Christianity stands or falls with the doctrine of the Trinity.
