Every worldview begins by answering one fundamental question: Who is God?
The answer to that question shapes everything else we believe. Our understanding of creation, morality, salvation, human dignity, sin, justice, and eternity all flow from our understanding of God Himself. If we misunderstand who God is, we will inevitably misunderstand ourselves and the world He has made.
The Christian faith does not begin with humanity’s search for God. It begins with God’s gracious revelation of Himself. Throughout history, people have worshiped countless gods, created idols with their hands, and imagined the divine according to their own wisdom. The Bible presents something entirely different. It tells the story of the one true God who has made Himself known.
This is why the doctrine of God stands at the beginning of every Christian confession of faith. Before we can understand why Christ came into the world, why humanity needs salvation, or why the Scriptures carry divine authority, we must first understand the One who created all things and has revealed Himself to us.
Christians believe there is only one God.
This conviction reaches back to the earliest pages of Scripture and remains unchanged throughout both the Old and New Testaments. Israel confessed, “Hear, O Israel: The LORD our God, the LORD is one” (Deuteronomy 6:4). Centuries later, the apostle Paul echoed the same truth, writing, “There is no God but one” (1 Corinthians 8:4).
The God of the Bible is not one among many competing deities. He is the eternal Creator of heaven and earth, existing before all things and depending upon nothing outside Himself. Everything that exists owes its existence to Him, while He owes His existence to no one. He was not created, cannot cease to exist, and is not limited by time, space, or the created order. As He declared to Moses from the burning bush, “I AM WHO I AM” (Exodus 3:14), revealing Himself as the self-existent and eternal One.
Yet the Christian understanding of God does not end with monotheism alone.
The same Scriptures that proclaim there is only one God also reveal that the Father is God, the Son is God, and the Holy Spirit is God. These are not three gods sharing a common purpose, nor are they merely different ways in which one person appears. Rather, the Bible reveals one divine being who eternally exists in three distinct Persons—Father, Son, and Holy Spirit.
This doctrine, known as the Trinity, is not the invention of later church councils or theologians. It is the conclusion the early church reached after carefully reading the whole counsel of Scripture. Christians did not create the doctrine of the Trinity; they confessed it because they believed it best reflected what God had revealed about Himself.
For that reason, our understanding of God begins not with human speculation but with divine revelation. We believe what we believe about God because He has made Himself known in creation, in His Word, and supremely through His Son, Jesus Christ.
God Has Revealed Himself
If God had chosen never to reveal Himself, humanity could never truly know Him.
We might speculate about His existence. We might observe the order of the universe and conclude that a Creator must exist. We might develop philosophies, religions, and moral systems in an attempt to understand the divine. But left to ourselves, we could never know who God is, what He is like, or what He requires of us.
The good news of Christianity is that God has not remained silent.
From the opening pages of Scripture to the final chapter of Revelation, the Bible presents a God who delights in making Himself known. He is not hidden because He is unwilling to be found. Rather, He has graciously revealed Himself so that His creatures might know Him, worship Him, and enjoy fellowship with Him.
The Bible describes this revelation in two primary ways: general revelation and special revelation.
General Revelation
General revelation refers to the knowledge of God that is available to every person through creation itself.
David declared,
«“The heavens declare the glory of God, and the sky above proclaims his handiwork.” (Psalm 19:1)»
Every sunrise, every mountain range, every ocean, every living creature, and every star in the heavens bears witness to the wisdom, power, and majesty of its Creator. Creation is not divine, nor should it be worshiped, but it continually points beyond itself to the One who made it.
The apostle Paul expands upon this truth in Romans 1. He teaches that God’s invisible attributes, His eternal power, and His divine nature have been clearly perceived in the things that have been made. As a result, humanity is “without excuse” (Romans 1:20). The created order testifies that there is a Creator.
General revelation also includes the moral awareness God has placed within mankind. Although cultures differ and consciences can become distorted by sin, people everywhere possess an awareness that certain things are right and others are wrong. Paul explains in Romans 2 that even those without the written Law demonstrate that God’s moral law is written upon their hearts, their consciences bearing witness to them.
General revelation is therefore sufficient to reveal that God exists and that humanity is accountable to Him.
It is not, however, sufficient to tell us how sinners can be reconciled to a holy God.
Creation can reveal God’s power, but it cannot tell us about the cross.
The stars proclaim His glory, but they do not proclaim the gospel.
For that, we need something more.
Special Revelation
Because humanity could never discover the gospel through observation alone, God has graciously revealed Himself through His Word.
Throughout history, God spoke through the prophets, revealing His character, His holiness, His purposes, and His plan of redemption. These revelations were recorded in the Scriptures, culminating in the coming of Jesus Christ.
The author of Hebrews writes,
«“Long ago, at many times and in many ways, God spoke to our fathers by the prophets, but in these last days he has spoken to us by his Son…” (Hebrews 1:1–2)»
Jesus Christ is the fullest revelation of God. He did not merely teach about God; He revealed Him. Jesus could say, “Whoever has seen me has seen the Father” (John 14:9) because He is the eternal Son who perfectly reveals the nature and character of God.
Today, we know Christ through the inspired Scriptures. The Bible is God’s completed revelation concerning His plan of redemption. It tells us who God is, why the world is broken, what Christ accomplished through His death and resurrection, and how sinners may be reconciled to God through faith.
This is why Christians treasure the Scriptures. They do not merely provide information about God; they introduce us to the God who has graciously made Himself known.
General revelation leaves humanity without excuse.
Special revelation leads us to Christ.
Both come from the same God, but only through His revealed Word do we come to know the gospel that brings salvation.
One God in Three Persons
Perhaps no doctrine distinguishes Christianity more clearly than the doctrine of the Trinity. It is also one of the most misunderstood.
Christians do not believe in three gods.
Neither do we believe that one Person merely appears in three different forms at different times.
Rather, the Bible reveals one God who eternally exists as three distinct Persons: the Father, the Son, and the Holy Spirit. Each Person is fully God. Each possesses the fullness of the divine nature. Yet there is only one God.
The word Trinity does not appear in the Bible. Like the words incarnation and omniscience, it is a theological term developed to summarize what the Scriptures teach. The doctrine was not invented by the early church; it was confessed because believers sought language that accurately reflected the testimony of Scripture.
The Bible repeatedly affirms that there is only one God.
Moses declared,
«“Hear, O Israel: The LORD our God, the LORD is one.” (Deuteronomy 6:4)»
Isaiah records the Lord saying,
«“I am the LORD, and there is no other, besides me there is no God.” (Isaiah 45:5)»
The New Testament echoes the same truth. Paul writes,
«“There is one God.” (1 Timothy 2:5)»
Biblical Christianity is, and always has been, uncompromisingly monotheistic.
Yet the same Scriptures also reveal that the Father is God.
Jesus consistently prayed to the Father, spoke of the Father’s will, and identified Him as God. No Christian disputes the deity of the Father.
The Son is likewise revealed as fully God.
John begins his Gospel with these remarkable words:
«“In the beginning was the Word, and the Word was with God, and the Word was God.” (John 1:1)»
Notice both truths held together. The Word was with God, showing distinction of Person, and the Word was God, affirming His full deity.
Thomas confessed the risen Christ,
«“My Lord and my God!” (John 20:28)»
Paul describes Jesus as,
«“…our great God and Savior Jesus Christ.” (Titus 2:13)»
Likewise, the Holy Spirit is revealed as fully divine.
In Acts 5, Peter rebuked Ananias for lying to the Holy Spirit and immediately explained,
«“You have not lied to man but to God.” (Acts 5:3–4)»
The Spirit possesses the attributes of God, performs the works of God, and receives the honor due to God alone.
Perhaps nowhere is the Trinity more beautifully displayed than at the baptism of Jesus.
As the Son came up from the water, the Holy Spirit descended upon Him like a dove, while the Father’s voice spoke from heaven:
«“This is my beloved Son, with whom I am well pleased.” (Matthew 3:16–17)»
The Father is not the Son.
The Son is not the Spirit.
The Spirit is not the Father.
Yet all three are present simultaneously, each acting according to His Person while sharing the one divine nature.
Jesus later commanded His disciples to baptize believers,
«“In the name of the Father and of the Son and of the Holy Spirit.” (Matthew 28:19)»
Notice that Jesus says name, not names. One divine name is shared by the three divine Persons.
The Trinity is not a mathematical equation to be solved but a truth to be confessed. Scripture does not explain exhaustively how one God exists eternally as three Persons. Instead, it reveals this reality, and Christians receive it by faith because it is what God has made known.
Throughout history, many illustrations have been offered to explain the Trinity—a shamrock, water existing as liquid, ice, and vapor, or the sun with its light and heat. While well intentioned, every analogy ultimately falls short and often unintentionally teaches error. God is unlike anything in creation. Rather than forcing Him into human comparisons, we are content to speak where Scripture speaks and remain silent where Scripture is silent.
The doctrine of the Trinity is not an abstract theological puzzle. It is the foundation of the gospel itself. The Father sent the Son. The Son accomplished redemption through His death and resurrection. The Holy Spirit applies that redemption to the hearts of believers. From eternity past to eternity future, the one true God has worked in perfect unity to accomplish His gracious plan of salvation.
To know the God of Scripture, therefore, is to know Him as He has revealed Himself: one eternal God, existing forever as Father, Son, and Holy Spirit.
The Attributes of God
Knowing that God exists is only the beginning. Scripture also reveals what God is like. These qualities, often called the attributes of God, are not characteristics He has acquired over time or qualities He may one day lose. They are the eternal perfections of His nature. God has always been who He is and always will be.
First, God is eternal.
Before the mountains were formed, before the stars filled the heavens, before time itself began, God already existed. Moses wrote,
«“Before the mountains were brought forth, or ever you had formed the earth and the world, from everlasting to everlasting you are God.” (Psalm 90:2)»
Everything in creation has a beginning. God alone is without beginning or end. He is the great “I AM,” existing independently of all that He has made.
God is also unchanging.
The world changes constantly. Nations rise and fall. People grow old. Circumstances shift from one day to the next. Even our own thoughts and emotions fluctuate. God does not.
The Lord declares,
«“For I the LORD do not change.” (Malachi 3:6)»
James likewise describes Him as the Father “with whom there is no variation or shadow due to change” (James 1:17). His character never improves because it is already perfect. His promises never fail because He is always faithful. The God who saved His people in ages past is the same God who saves today.
Scripture also teaches that God is all-powerful.
Nothing can frustrate His purposes or overcome His will. He created the universe by His word, sustains all things by His power, and accomplishes everything He has determined. Jeremiah confessed,
«“Ah, Lord GOD! It is you who have made the heavens and the earth by your great power… Nothing is too hard for you.” (Jeremiah 32:17)»
God’s power, however, is never separated from His wisdom or His goodness. He never acts irrationally or unjustly. Everything He does is consistent with His perfect character.
God is also all-knowing.
Nothing escapes His attention. He knows every star by name, every sparrow that falls, every word before it is spoken, and every thought before it enters our minds. The psalmist marveled,
«“O LORD, you have searched me and known me.” (Psalm 139:1)»
God has never learned anything because there has never been anything He did not know. Past, present, and future are fully known to Him.
The Scriptures also reveal that God is everywhere present.
This does not mean that God is identical with creation, as pantheism teaches. Rather, it means that no place exists where God is absent. David wrote,
«“Where shall I go from your Spirit? Or where shall I flee from your presence?” (Psalm 139:7)»
Whether we stand upon the highest mountain or descend into the deepest valley, God is there. His presence comforts His people and reminds us that we are never beyond His care.
Above all, Scripture emphasizes God’s holiness.
The seraphim surrounding His throne cry continually,
«“Holy, holy, holy is the LORD of hosts.” (Isaiah 6:3)»
God is utterly separate from sin. He is morally perfect in every way. His holiness is not merely one attribute among many; it defines everything He is. His love is a holy love. His justice is holy justice. His mercy is holy mercy.
Because God is holy, He cannot overlook sin. His justice demands that evil be judged. Yet because He is also rich in mercy and steadfast in love, He provided the very salvation that His justice required through the death and resurrection of His Son.
The Bible repeatedly celebrates God’s love.
John writes simply,
«“God is love.” (1 John 4:8)»
God’s love is not sentimental or permissive. It is a holy love that seeks the good of His people and was demonstrated most clearly at the cross, where Christ gave Himself for sinners. God’s justice and God’s love are not opposing qualities. They meet perfectly in Jesus Christ, where God’s righteous judgment against sin and His gracious mercy toward sinners are displayed together.
Every attribute of God exists in perfect harmony with every other attribute. God is never more loving than He is holy, never more merciful than He is just, never more powerful than He is wise. His perfections never compete with one another because they all belong to the one perfect God.
As we grow in our understanding of God’s character, our response should not merely be greater knowledge but greater worship. The purpose of theology is not simply to fill our minds with facts about God. It is to lead us to love Him, trust Him, obey Him, and stand in awe of the One who alone is worthy of all glory, honor, and praise.
Why the Doctrine of God Matters
It is possible to know many facts about God without truly knowing God.
A person may understand the doctrine of the Trinity, memorize the attributes of God, and defend orthodox theology with great skill, yet still fail to love the One those doctrines describe. Theology was never intended to produce pride. Properly understood, it produces worship.
The doctrine of God is not an abstract subject reserved for theologians and seminary classrooms. It shapes every aspect of the Christian life.
Because God is eternal, we can trust Him when our lives seem uncertain.
Because God is unchanging, His promises remain as certain today as they were when they were first spoken.
Because God is all-powerful, nothing can frustrate His purposes for His people.
Because God is all-knowing, He understands every sorrow, every temptation, and every burden we carry.
Because God is holy, we learn to hate sin and pursue righteousness.
Because God is loving, we have confidence that He desires the good of His children.
Because God is just, we know that evil will not have the final word.
Every truth about God gives us another reason to trust Him.
Our understanding of salvation also begins here. We are not saved because God overlooked our sin or ignored His justice. Nor are we saved because we somehow earned His favor. We are saved because the holy, just, and loving God accomplished our redemption through Jesus Christ. At the cross, God’s justice against sin and His mercy toward sinners were displayed together in perfect harmony.
This is why Christians worship God rather than merely admire Him.
He alone is worthy of our worship because He alone is the Creator. Every breath we take, every blessing we enjoy, and every moment of our existence depends upon Him. We were created by Him and for Him. Our greatest purpose is not self-fulfillment but to glorify God and enjoy Him forever.
The doctrine of God also protects the church from error. Throughout history, false teachings have almost always begun by distorting God’s character. Some portray Him as loving but not holy. Others emphasize His justice while forgetting His mercy. Some diminish the deity of Christ. Others deny the personhood of the Holy Spirit. Still others reshape God into the image of human culture or personal preference.
The God of Scripture refuses to be remade in our image.
Instead, He calls us to be transformed into His.
For that reason, Christians must continually return to the Scriptures. Our understanding of God must be shaped by what He has revealed about Himself rather than by our feelings, traditions, or imaginations. We do not create our own picture of God and ask Him to fit it. We humbly receive the revelation He has given.
The more clearly we see God, the more clearly we see ourselves. His holiness exposes our sin. His grace reveals our hope. His sovereignty gives us peace. His faithfulness strengthens our confidence. His love draws us near through Jesus Christ.
To know God is the greatest privilege anyone can possess.
Jesus prayed,
«“And this is eternal life, that they know you, the only true God, and Jesus Christ whom you have sent.” (John 17:3)»
Eternal life is not merely living forever. It is knowing the God who made us, redeemed us, and has promised to dwell with His people forever.
For that reason, the study of God is not the end of the Christian life—it is the beginning of it. Every page of Scripture, every doctrine we confess, and every act of worship ultimately leads us back to the One from whom all things came and for whom all things exist. To Him alone be glory forever.
Conclusion
Everything Christians believe begins with God.
Before there was creation, there was God.
Before there was sin, there was God.
Before there was a promise of redemption, there was God.
He alone is eternal, self-existent, holy, and unchanging. He created all things, sustains all things, and governs all things according to His perfect wisdom and purpose. He has not hidden Himself from His creation but has graciously revealed Himself through the world He made, through the Scriptures He inspired, and most fully through His Son, Jesus Christ.
The God of the Bible is not a distant force or an impersonal power. He is the living God who calls people into a relationship with Himself. He is the Father who planned our redemption, the Son who accomplished it through His death and resurrection, and the Holy Spirit who applies it to the hearts of believers. Though we cannot fully comprehend the infinite God, we can truly know Him because He has chosen to make Himself known.
For this reason, our understanding of God is not shaped by popular opinion, personal preference, or human imagination. It is shaped by divine revelation. We gladly submit our thoughts to what God has spoken about Himself, trusting that the One who knows all things has revealed exactly what we need to know for life and godliness.
As we grow in our knowledge of God, may our worship deepen, our faith become stronger, and our lives increasingly reflect His character. May we never lose our sense of awe before the God who is infinitely holy, perfectly just, immeasurably loving, and worthy of all praise.
«“For from him and through him and to him are all things. To him be glory forever. Amen.” (Romans 11:36)»
A Prayer
Heavenly Father,
We praise You because You alone are God. Before the foundations of the world were laid, You were. You are the Creator of heaven and earth, the giver of life, and the One who upholds all things by Your power.
Thank You for revealing Yourself to us. Thank You for making Yourself known through creation, through Your Word, and most fully through Your Son, Jesus Christ. Left to ourselves we could never have known You, but in Your grace You have drawn near to us.
Help us to worship You as You truly are, not as we imagine You to be. Guard us from creating You in our own image, and instead transform us into the image of Christ. Give us humble hearts that gladly submit to Your truth and joyfully obey Your will.
Teach us to trust Your wisdom when we do not understand, to rest in Your sovereignty when life is uncertain, to rejoice in Your love when we are discouraged, and to pursue holiness because You are holy.
May our knowledge of You never remain merely intellectual. Let it produce deeper faith, greater obedience, sincere worship, and a growing love for You and for those You have created.
To You alone belong all glory, honor, dominion, and praise, now and forever.
In the name of the Father, and of the Son, and of the Holy Spirit,
Amen.
