Who Is God?
The Living God Who Has Made Himself Known
Every doctrine begins with God.
Before the church can rightly speak of salvation, Scripture, the gospel, the Spirit, the church, judgment, holiness, or love, it must first answer a prior question. Who is God? Every other doctrine assumes some answer to it. If the answer is distorted, everything downstream is distorted with it.
The first question is not merely whether we believe that God exists. Even the demons believe that (James 2:19). The deeper question is whether we will allow God to define Himself by His own revelation, or whether we will fashion a god according to preference, philosophy, feeling, or inherited tradition.
Scripture does not invite us to imagine God. It calls us to receive Him. It presents a God who has spoken, acted, judged, redeemed, and made Himself known. He is not the conclusion of human speculation. He is the living God who has revealed Himself, and He must be known on His own terms.
God Is Not Discovered; He Is Revealed
The nations have always tried to reach God by climbing upward — through philosophy, ritual, imagination, and religious effort. Scripture reverses the direction. God is known because He has come down, spoken, and disclosed Himself.
Paul told the Athenians that God does not dwell in temples made with hands, nor is He served by human hands as though He needed anything. He made every nation and set the times and boundaries of their dwelling:
“So that they should seek the Lord, in the hope that they might grope for Him and find Him, though He is not far from each one of us.” — Acts 17:27, NKJV
Notice the word grope. Left to ourselves, we feel in the dark. But God has not left us in the dark. He has spoken.
This is the difference between the God of Scripture and the gods of human religion. The idols are made in the image of man’s imagination. The living God reveals Himself and forbids us to remake Him:
“You shall not make for yourself a carved image.” — Exodus 20:4, NKJV
The second commandment is not only about statues. It is about the human tendency to reshape God into something more manageable, more comfortable, more useful. To know God rightly, we must let Him define Himself.
How God Has Made Himself Known
God has revealed Himself in creation, in covenant, in Scripture, and supremely in Jesus Christ.
He has revealed Himself in creation. The heavens are not silent:
“The heavens declare the glory of God; and the firmament shows His handiwork.” — Psalm 19:1, NKJV
Paul says this witness is enough to leave humanity without excuse:
“For since the creation of the world His invisible attributes are clearly seen, being understood by the things that are made, even His eternal power and Godhead, so that they are without excuse.” — Romans 1:20, NKJV
Creation testifies that God is, that He is powerful, and that He is the Maker. But creation does not tell us His name, His covenant, His mercy, or His plan of salvation. For that, God had to speak.
He has revealed Himself in covenant and in Scripture. He called Abraham, redeemed Israel, gave the Law, spoke through the prophets, and recorded His acts and words so they would be known in every generation. He did not merely act in history. He interpreted His acts through His word, so that His people would know not only what He did, but who He is.
And supremely, He has revealed Himself in His Son. Every earlier revelation was preparatory. The fullness came in Christ:
“God, who at various times and in various ways spoke in time past to the fathers by the prophets, has in these last days spoken to us by His Son.” — Hebrews 1:1–2, NKJV
Who God Has Revealed Himself to Be
When Moses asked for God’s name, God answered with a self-existent declaration:
“I AM WHO I AM.” — Exodus 3:14, NKJV
God is not one being among many. He does not depend on anything outside Himself. He simply is. He is the source of all existence, the uncreated Creator, the One who was, and is, and is to come.
But God did more than declare His existence. He proclaimed His character. When He passed before Moses, He announced who He is:
“The Lord, the Lord God, merciful and gracious, longsuffering, and abounding in goodness and truth, keeping mercy for thousands, forgiving iniquity and transgression and sin, by no means clearing the guilty.” — Exodus 34:6–7, NKJV
This is one of the most important self-revelations in all of Scripture. In a single breath God declares mercy, grace, patience, goodness, truth, faithfulness, forgiveness — and justice that will not clear the guilty. He is not a collection of competing traits. He is one God whose character holds together perfectly.
We do not get to isolate one attribute and build a god from it. The God who is love is also holy. The God who forgives is also just. The God who is patient is also true. He must be received whole.
God Is Holy
The word that echoes around the throne of God is not “loving, loving, loving,” nor “mighty, mighty, mighty,” but:
“Holy, holy, holy is the Lord of hosts; the whole earth is full of His glory!” — Isaiah 6:3, NKJV
To be holy is to be set apart, wholly other, transcendent in purity. God’s holiness is His absolute separation from all sin and His perfect moral purity. He is not merely better than us by degrees. He is holy in a way that exposes the uncleanness of even the most righteous person.
When Isaiah saw the holiness of God, he did not feel affirmed. He fell apart:
“Woe is me, for I am undone! Because I am a man of unclean lips.” — Isaiah 6:5, NKJV
The holiness of God is why sin is serious, why judgment is real, and why salvation had to come at the cost of the cross. A god who was not holy could overlook sin cheaply. The true God cannot, because He is of purer eyes than to behold evil (Habakkuk 1:13).
And because God is holy, He calls His people to holiness:
“Be holy, for I am holy.” — 1 Peter 1:16, NKJV
God Is Love
Scripture also declares, with equal force, that God is love:
“He who does not love does not know God, for God is love.” — 1 John 4:8, NKJV
But the Bible does not leave “love” to be defined by sentiment, culture, or feeling. It defines the love of God by a concrete act:
“In this the love of God was manifested toward us, that God has sent His only begotten Son into the world, that we might live through Him. In this is love, not that we loved God, but that He loved us and sent His Son to be the propitiation for our sins.” — 1 John 4:9–10, NKJV
God’s love is not indulgence. It is not the mere approval of whatever we are. It is a costly, self-giving love that sent the Son to bear the guilt of our sin. Divine love does not ignore holiness; it satisfies holiness at the cross so that sinners can be reconciled without God ceasing to be just.
This means love and holiness are not rivals in God. The same God who is holy is love, and the clearest display of both is the cross.
How the Attributes Belong Together
Much error about God comes from tearing His attributes apart — taking love without holiness, or wrath without mercy, or sovereignty without goodness — and building a lopsided god from the fragment.
Scripture will not allow it. In Exodus 34 God proclaims mercy and justice in the same sentence. He is longsuffering, yet He will by no means clear the guilty. He forgives iniquity, yet He does not treat sin as nothing.
The place where every attribute meets without contradiction is the cross. There God’s justice against sin and His mercy toward sinners are displayed together:
“Whom God set forth as a propitiation by His blood, through faith… that He might be just and the justifier of the one who has faith in Jesus.” — Romans 3:25–26, NKJV
At the cross God is just — sin is punished, not excused. And God is the justifier — the sinner is forgiven, not condemned. Holiness is honored. Love is poured out. Wrath falls on the substitute. Mercy reaches the guilty. Faithfulness keeps the promise. Patience waited for the appointed time.
A right doctrine of God holds all of this together. His wrath is not the opposite of His love; it is His holy love in the presence of evil. His patience is not weakness; it is mercy giving time for repentance (2 Peter 3:9). His faithfulness is not passivity; it is the certainty that He will keep every word He has spoken:
“God is not a man, that He should lie… has He said, and will He not do?” — Numbers 23:19, NKJV
God Is One, and God Is Triune
The confession of Israel is that God is one:
“Hear, O Israel: The Lord our God, the Lord is one!” — Deuteronomy 6:4, NKJV
There is one God. Not many. The living God is unrivaled, and He will not share His glory with another (Isaiah 42:8).
Yet within the revelation of the one God, Scripture speaks of the Father, the Son, and the Holy Spirit — each fully God, distinct in person, united in essence, will, and glory. This is not the church inventing a doctrine. It is the church confessing what the apostolic witness reveals.
The Father sends. The Son is the eternal Word who became flesh. The Spirit proceeds and dwells. When Jesus commissioned His apostles, He named all three within a single name:
“Baptizing them in the name of the Father and of the Son and of the Holy Spirit.” — Matthew 28:19, NKJV
Not names, plural — name, singular. One God, revealed as Father, Son, and Spirit. Paul closes his letter to Corinth the same way:
“The grace of the Lord Jesus Christ, and the love of God, and the communion of the Holy Spirit be with you all.” — 2 Corinthians 13:14, NKJV
The doctrine of the Trinity is not a riddle to be solved but a revelation to be received. God is one in being and three in persons. We confess it because Scripture reveals it, and because the God who saves us is the Father who sends, the Son who redeems, and the Spirit who dwells within.
The Father Revealed Through the Son
No one has ever fully seen God the Father directly. But He has not remained hidden:
“No one has seen God at any time. The only begotten Son, who is in the bosom of the Father, He has declared Him.” — John 1:18, NKJV
The Son is the exact revelation of the Father’s character:
“Who being the brightness of His glory and the express image of His person.” — Hebrews 1:3, NKJV
“He is the image of the invisible God, the firstborn over all creation.” — Colossians 1:15, NKJV
This is why Jesus could say to Philip:
“He who has seen Me has seen the Father.” — John 14:9, NKJV
If you want to know what God is like — His heart toward sinners, His hatred of evil, His compassion for the broken, His authority over creation, His truthfulness, His holiness — look at Jesus Christ. He is not a partial or distorted picture. He is the exact representation.
Jesus Christ, the Full and Final Revelation of God
In Christ, the fullness of God was not merely reflected but embodied:
“For in Him dwells all the fullness of the Godhead bodily.” — Colossians 2:9, NKJV
“And the Word became flesh and dwelt among us, and we beheld His glory, the glory as of the only begotten of the Father, full of grace and truth.” — John 1:14, NKJV
This is the climax of divine revelation. God spoke through prophets, but finally He spoke through His Son. The Son is not a messenger about God; He is God the Son, come in the flesh, making the invisible God known.
This means the knowledge of God is not open-ended speculation that each generation reinvents. It has a fixed center. To know God is to know the Father through the Son, by the Spirit, as revealed in Scripture. Any doctrine of God that diminishes Christ, bypasses Christ, or reshapes God into something other than the One revealed in Christ has departed from the revelation itself.
The Holy Spirit: God Present, Convicting, Sanctifying, Indwelling
God has not only spoken to His people from outside; by His Spirit He dwells among them and within them. The Holy Spirit is not an impersonal force or influence. He is God, personally present.
The Spirit convicts:
“And when He has come, He will convict the world of sin, and of righteousness, and of judgment.” — John 16:8, NKJV
The Spirit indwells the believer, making the body a temple:
“Do you not know that your body is the temple of the Holy Spirit who is in you, whom you have from God?” — 1 Corinthians 6:19, NKJV
The Spirit marks those who belong to Christ:
“Now if anyone does not have the Spirit of Christ, he is not His.” — Romans 8:9, NKJV
Through the Spirit, God reveals, convicts of sin, sanctifies His people, seals them, and dwells among them. The God who is holy and transcendent is also, by His Spirit, near — present with His people, at work in them, conforming them to the image of His Son.
Worshiping God in Spirit and Truth
Because of who God is, worship is not optional and it is not to be offered on our own terms. Jesus told the woman at the well that a new hour had come:
“But the hour is coming, and now is, when the true worshipers will worship the Father in spirit and truth; for the Father is seeking such to worship Him. God is Spirit, and those who worship Him must worship in spirit and truth.” — John 4:23–24, NKJV
Worship must be in spirit — genuine, from the heart, not mere external ritual. And it must be in truth — according to who God has revealed Himself to be, not according to human invention. Sincerity is not enough if it worships a god who does not exist. Correctness is not enough if the heart is cold. True worship joins a heart engaged by the Spirit to a mind governed by the truth God has revealed.
This is why the doctrine of God is not a cold academic matter. To know God rightly is to worship Him rightly. A distorted view of God produces distorted worship. A true view of God produces reverence, awe, gratitude, and obedience.
Why the Doctrine of God Governs Everything
The doctrine of God is not one topic among many. It is the foundation beneath every other doctrine.
If we misunderstand God’s holiness, we will misunderstand sin, judgment, and the seriousness of salvation. If we misunderstand God’s love, we will either sentimentalize grace or despair of mercy. If we misunderstand God’s justice, we will either deny His wrath or lose His compassion. If we misunderstand the Trinity, we will misunderstand the Son and the Spirit, and the whole gospel unravels. If we misunderstand God’s faithfulness, we will not trust His promises.
Our understanding of salvation, Scripture, the church, grace, holiness, obedience, and worship will all be shaped — rightly or wrongly — by our understanding of God. This is why Scripture guards the knowledge of God so jealously, and why every idol and every distortion is confronted so directly.
Get God wrong, and everything bends around the error. Receive God as He has revealed Himself, and the rest of doctrine finds its center.
Conclusion: Begin With the Living God
Truthscape begins here — not with man’s religious systems, philosophical constructions, or inherited assumptions, but with the living God who has revealed Himself in creation, in covenant, in Scripture, and supremely in Jesus Christ.
He is the great I AM, self-existent and eternal. He is holy, holy, holy. He is love, displayed at the cross. He is merciful and gracious, longsuffering, abounding in goodness and truth, forgiving iniquity, yet by no means clearing the guilty. He is one God, revealed as Father, Son, and Holy Spirit. He has made Himself known in His Son, and He dwells among His people by His Spirit.
We do not get to invent Him. We do not get to edit Him. We do not get to reshape Him into something more comfortable. We are called to receive Him as He is, to worship Him in spirit and truth, and to let the knowledge of God reorder our doctrine, our obedience, our worship, and our lives.
God is not discovered by speculation.
He is known because He has made Himself known.
Begin here. Know the God who has spoken — and let every other doctrine be measured by Him.
