The God of the Bible — the One the whole book points back to.

Thrown into the furnace by a king who had just demanded the whole province bow to his image, three Hebrew captives heard the most defiant question in the Old Testament hurled at the God of heaven Himself:

“…and who is that God that shall deliver you out of my hands?”

— Daniel 3:15, KJV

Who is that God? It is the oldest question there is, and the one the whole Bible is written to answer. Get it wrong and everything downstream bends — how you worship, who you trust, what you become. Moses warned Israel that this was the one thing they must never forget: “if thou do at all forget the LORD thy God, and walk after other gods, and serve them, and worship them… ye shall surely perish” (Deuteronomy 8:19). To forget who God is, is to end up serving a counterfeit without ever noticing the substitution. So the question deserves a careful answer — and the Bible is not shy about giving one.

Jesus put the stakes plainly. Asked what eternal life actually is, He did not describe a place or a length of days. He defined it as a relationship with two specific persons:

“And this is life eternal, that they might know thee the only true God, and Jesus Christ, whom thou hast sent.”

— John 17:3, KJV

Eternal life is to know the only true God and Jesus Christ whom He sent. Two persons, named and distinguished, in the same breath. Everything in this study grows from that one verse.

The counterfeit in the furnace

Before we build that positive case, look once more at the scene we started in — because it sets the terms for everything that follows. The king’s demand was not vague paganism. When Nebuchadnezzar charged the three Hebrews with refusing to serve “my gods” (Daniel 3:14), the plural was exact. Babylon’s religion was built around a triad of high deities — Anu of the heavens, Bel (a title borne by Marduk, Babylon’s chief god), and Ea of the deep — among whom the priests divided all things. Jeremiah names two of them in his oracle against the city: “Babylon is taken, Bel is confounded, Merodach [Marduk] is broken in pieces” (Jeremiah 50:2). The demand on the plain of Dura was, at bottom, a demand to bow to a three-in-one godhead in place of the one true God.

And that triadic pattern is older than Babylon and wider than it — a recurring shape in the religions of antiquity that even secular students of myth have noticed long predates the Christian centuries. The full history of how a three-in-one construction traveled down into later Christendom is a study of its own (a companion article in this section traces it). What matters here is the contrast Daniel draws so sharply: the three Hebrews refused the triad, confessed the one God and His Son, and were met in the fire by a fourth “like the Son of God.” The question “who is that God?” was never really about the music or the hour or the golden image. It was about which God — the counterfeit many, or the true One and His Son — and on whose authority; the same contest the last pages of the Bible say will be forced on the whole world again. So let us set the counterfeit aside and let Scripture name the real One, beginning where it tells us to begin: with the highest witness there is.

Let Him answer in His own words

On a question this important we should not run on rumor — on what someone said someone said, on a formula inherited and never checked. We should go to the highest source. And there is exactly one being who came from heaven for the express purpose of telling us who God is:

“No man hath seen God at any time; the only begotten Son, which is in the bosom of the Father, he hath declared him.”

— John 1:18, KJV

So we will let Jesus answer. What did He say the first and greatest truth is? When a scribe — a man whose whole occupation was copying the Scriptures by hand — tested Him with the question, “which is the first commandment of all?”, Christ did not begin with “love God.” He began one step further back, with the identity of God:

“The first of all the commandments is, Hear, O Israel; The Lord our God is one Lord: and thou shalt love the Lord thy God with all thy heart…”

— Mark 12:29-30, KJV

Before the command to love comes the fact to know: the Lord our God is one. You cannot love with all your mind a God you have not bothered to identify. And notice the scribe’s reply — Jesus commended it as correct, telling him he was “not far from the kingdom of God”: “there is one God; and there is none other but he” (Mark 12:32). One God. None other.

So who is that one God they were both speaking of? We do not have to guess; Jesus says it outright. To the very people who claimed the Shema as their own, He said:

“…It is my Father that honoureth me; of whom ye say, that he is your God.”

— John 8:54, KJV

The God of the Jews — the one God of “the Lord our God is one Lord” — is the Father. Jesus confirms it again, naming the Father as the supreme sovereign: “I thank thee, O Father, Lord of heaven and earth” (Matthew 11:25). And when He told the woman at the well who true worship is directed to, He pointed to the same person: “the true worshippers shall worship the Fatherin spirit and in truth: for the Father seeketh such to worship him” (John 4:23). When He taught His disciples to pray, the address was “Our Father which art in heaven.” Prayer is worship, and Christ directed it to the Father.

The men He sent agree

If this is what Jesus taught, the men He sent cannot contradict Him — and they do not. James notes even the demons get the arithmetic right: “Thou believest that there is one God; thou doest well: the devils also believe, and tremble” (James 2:19). Paul, writing to Timothy, sets the one God beside the one mediator without collapsing the two:

“For there is one God, and one mediator between God and men, the man Christ Jesus.”

— 1 Timothy 2:5, KJV

And then Paul spells it out so plainly it can hardly be misread — identifying the one God by name, and Christ in His own distinct place:

“But to us there is but one God, the Father, of whom are all things, and we in him; and one Lord Jesus Christ, by whom are all things, and we by him.”

— 1 Corinthians 8:6, KJV

To us there is but one God — the Father. It is the same two-fold pattern as John 17:3: one God the Father, and one Lord Jesus Christ. Paul keeps it consistent elsewhere — “the head of Christ is God” (1 Corinthians 11:3), and “one God and Father of all, who is above all, and through all, and in you all” (Ephesians 4:6). The witness is uniform from the Gospels through the epistles: the one true God is the Father, an individual being, and the true worshippers worship Him.

“But isn’t Elohim plural?”

Here someone usually raises the one objection that sounds technical enough to settle the matter: the Hebrew word for God, Elohim, is grammatically plural — therefore God must be more than one. It is true that Elohim is the plural form of El. But we let the Bible interpret its own language, and the Bible uses that plural for plainly singular subjects. When God commissioned Moses, He said:

“See, I have made thee a god [Elohim] to Pharaoh: and Aaron thy brother shall be thy prophet.”

— Exodus 7:1, KJV

Was Moses split into several persons and sent to Pharaoh? Obviously not. The same book tells us what the plural conveyed: “the man Moses was very great in the land of Egypt” (Exodus 11:3). This is the Hebrew plural of majesty — a plural form used of a single subject to denote not multiplicity but greatness. Applied to the one true God, Elohim does not teach that God is more than one; it teaches that God is very great. The grammar does not overturn the dozen plain statements; it agrees with them.

Then who is the Son?

If the Father is the only true God, the honest next question is the one eternal life hangs on: then who is Christ? He told us plainly what He claimed to be — “Say ye of him, whom the Father hath sanctified, and sent into the world, Thou blasphemest; because I said, I am the Son of God?” (John 10:36). The Son of God. And of all the things the Father could have announced from heaven, this is the one He chose to say out loud — not once but twice:

“And lo a voice from heaven, saying, This is my beloved Son, in whom I am well pleased.”

— Matthew 3:17, KJV

The Father speaks audibly from heaven only a handful of times in the whole New Testament — at the baptism (Matthew 3:17), at the transfiguration (“This is my beloved Son … hear ye him,” Matthew 17:5), and before the Greeks (John 12:28). He could have delegated the message to an angel; He did not. He said it Himself, and He repeated it. That is the measure of how much weight heaven puts on it. Peter confessed the same truth — “Thou art the Christ, the Son of the living God” — and Christ answered that flesh and blood had not revealed it, but the Father, and that on this rock He would build His church (Matthew 16:16-18). The first sermon Paul ever preached was simply “that he is the Son of God” (Acts 9:20). It is the rock the church stands on.

And it is the very thing the Jews moved to kill Him for — which tells us how much it means:

“…because he not only had broken the sabbath, but said also that God was his Father, making himself equal with God.”

— John 5:18, KJV

Read that carefully, because it carries the whole argument. Christ’s equality with God is not asserted againstHis Sonship — it is grounded in it. He is equal with God because God is His Father. That is the hinge the rest of the study turns on.

In what sense “begotten”?

Scripture calls several kinds of beings “sons of God,” so we have to ask in what sense Christ is the Son. The angels are sons of God by creation (Job 38:7). Believers become sons of God by adoption (Romans 8:15; 1 John 3:1). Christ is in neither category. He is, in a class entirely His own, the only begotten:

“For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life.”

— John 3:16, KJV

Not created like the angels, not adopted like us — begotten, which means born of, brought forth from. And begotten of whom? “The glory as of the only begotten of the Father” (John 1:14). When? Long before Bethlehem. Micah, prophesying where Messiah would be born, says His existence reaches back past that birth entirely — “whose goings forth have been from of old, from everlasting” (Micah 5:2), the word for goings forth carrying the sense of origin or descent. Solomon, under the figure of wisdom (which Paul identifies as Christ, 1 Corinthians 1:24), points to the same deep past:

“I was set up from everlasting, from the beginning, or ever the earth was… before the mountains were settled … was I brought forth.”

— Proverbs 8:23-25, KJV

Twice in that passage — as twice the Father said “this is my Son” — the word is brought forth: born, begotten, before anything was made. And being begotten of the Father before creation, He was not Himself created; rather, it was through Him that everything else was. “God… created all things by Jesus Christ” (Ephesians 3:9); “by him were all things created… and he is before all things” (Colossians 1:16-17); “all things were made by him” (John 1:3). He pre-exists time and matter. He was begotten of God in eternity, and — “when the fulness of the time was come” — born of a woman in history (Galatians 4:4), the only being who is, in the fullest sense, both the Son of God and the Son of Man.

And lest anyone think this is a New Testament novelty: the Old Testament knew God had a Son. “Unto us a son is given” (Isaiah 9:6). “What is his name, and what is his son’s name, if thou canst tell?” (Proverbs 30:4). “Kiss the Son, lest he be angry” (Psalm 2:12). Even a heathen king, watching the furnace, saw it: “the form of the fourth is like the Son of God” (Daniel 3:25) — because the captives had told him their God had a Son.

What the Son inherited — and why it exalts Him

Here is where the doctrine stops being abstract. A son inherits from his father. What did this Son inherit?

“Who being the brightness of his glory, and the express image of his person… being made so much better than the angels, as he hath by inheritance obtained a more excellent name than they.”

— Hebrews 1:3-4, KJV

A more excellent name, by inheritance. And “name” in Scripture means far more than a label — it carries authority, character, and nature. When God proclaimed His name to Moses, He recited His character: “The LORD, The LORD God, merciful and gracious, longsuffering, and abundant in goodness and truth” (Exodus 34:6). So the Son inheriting the Father’s name means He inherited the Father’s very nature — as any son inherits his father’s nature. A child born of human parents is human; the Son born of God is divine. That is exactly why Hebrews says He is greater than the angels: He has the divine nature of His Father. “As the Father hath life in himself; so hath he given to the Son to have life in himself” (John 5:26). “In him dwelleth all the fulness of the Godhead bodily” (Colossians 2:9). Being “in the form of God,” He “thought it not robbery to be equal with God” (Philippians 2:6).

This is the point most often gotten backwards. To confess that Christ is the literally begotten Son of God is not to make Him less — it is the only ground Scripture gives for His being fully divine and equal with the Father at all. Deny the begetting, and you have cut away the very root the Bible plants His deity in. That is why Jesus said, “that all men should honour the Son, even as they honour the Father. He that honoureth not the Son honoureth not the Father” (John 5:23). We honor Him no less than the Father — we honor Him precisely as the only begotten Son of God. To insist He must be God in some way that erases His Sonship is, oddly, to dishonor Him.

And the Spirit?

This is the question that always follows, and the Bible’s answer is simpler than tradition makes it. We are not probing the deep nature of the Spirit here — only its identity, and for that we let the Bible define its own term. What is “spirit”? Isaiah asks, “Who hath directed the Spirit of the LORD?” (Isaiah 40:13) — and Paul, quoting that exact verse, renders it “Who hath known the mind of the Lord?” (Romans 11:34). Spirit, here, is mind. And a person’s mind is not a second person standing beside him. When “Nebuchadnezzar dreamed dreams, wherewith his spirit was troubled” (Daniel 2:1), it was he who was troubled, in himself — not somebody else in the next room. Paul draws the analogy out exactly:

“For what man knoweth the things of a man, save the spirit of man which is in him? even so the things of God knoweth no man, but the Spirit of God.”

— 1 Corinthians 2:11, KJV

Even so — in the same way. As a man’s spirit is the man’s own self, so the Spirit of God is God’s own self: His mind, His character, His presence. And whose Spirit is it? Paul uses the terms interchangeably in a single breath: “the Spirit of God” and “the Spirit of Christ,” and then “Christ in you” — all the same indwelling (Romans 8:9-10). There is “one Spirit” (Ephesians 4:4), shared by the Father and the Son. So when we receive the Spirit, who do we receive?

“…If a man love me, he will keep my words: and my Father will love him, and we will come unto him, and make our abode with him.”

— John 14:23, KJV

Not a third party arriving in their place — the Father and the Son themselves, coming by their Spirit. That is why Jesus, promising the Comforter, could say in the same chapter, “I will not leave you comfortless: I will come to you” (John 14:18), and why Paul states flatly, “Now the Lord is that Spirit” (2 Corinthians 3:17). The Comforter is Christ’s own presence returned to His people. The fuller treatment of this belongs to its own study in this section; here it is enough to see that the Spirit is the personal presence of the Father and the Son, not a separate third being.

A note on what is being critiqued

The argument of this study is with a doctrinal construction — not with the people who hold it. The vast majority of sincere Christians who confess a three-in-one God have simply received the formula as it was handed to them, in good faith, never having examined it from the Scriptures for themselves. They love God as well as they know how, and God “takes the knowledge that they have and judges according to the knowledge that they have.” Every Christian tradition has held worshippers Christ calls His own. The quarrel here is with a teaching, never with neighbours — and the aim is not to win a debate but to hold up the plain reading of the text so that anyone who loves the true God can recognize Him more clearly and come nearer. If anything here reads as scorn for persons rather than care for the truth, it is written badly, and the fault is mine.

Why it matters

Return to where we began. Eternal life, Jesus said, is to know “the only true God, and Jesus Christ, whom thou hast sent” (John 17:3). Not a formula to recite — two persons to know: the Father, the one true God of the whole Bible, and His only begotten Son, equal with Him because born of Him, who came to declare Him and to bring us home, present with us now by their one Spirit. This is not obscure knowledge reserved for scholars. It is the plain testimony of Christ, the apostles, the prophets, and even — in the end — a humbled heathen king, who came out of that encounter with the furnace confessing what he had so recently mocked:

“…there is no other God that can deliver after this sort.”

— Daniel 3:29, KJV

There is no other. To know that God — the Father, through His only begotten Son, by their Spirit — is the whole of eternal life, and the answer the book has been giving from Deuteronomy to the furnace to the cross. The question Nebuchadnezzar threw down in scorn is the one each of us finally has to answer for ourselves: who is that God— and will you worship Him, and no other?
