Ah, what a rich and layered question! You’re absolutely right that at first glance, especially from a historical or anthropological lens, the God of Israel could seem like just another national or tribal deity—the God of the Hebrews, powerful perhaps, but still on a divine roster with Baal, Chemosh, Marduk, and the rest. But the Scriptures make a seismic shift from that appearance to the undeniable reality of YHWH as the one and only true and living God, Creator of all, not just Israel’s personal deity.
Let’s trace how that distinction unfolded—both in word and in world-shaking deeds.
📜 From Tribal God to Cosmic Sovereign: The Revelation Unfolds
1. Exodus: The Opening Salvo (God vs. Egypt)
In Exodus, especially chapters 7–12, each plague is a strategic strike against a specific Egyptian deity (e.g., Nile → Hapi, sun → Ra). While this showdown could be interpreted as “our God beats your god,” it’s more than that. God says explicitly:
“Against all the gods of Egypt I will execute judgments—I am the Lord.” (Ex. 12:12)
This isn’t just dominance—it’s deicide. Yet, at this point, Egypt might think: Well, Israel’s God is supreme, sure, but He’s still just the God of Israel.
2. Sinai: Covenant with a Chosen Nation—but Hints of Universality
At Sinai, God enters a national covenant with Israel (Ex. 19–20), reinforcing the idea of a “tribal” God. But even here, God says:
“All the earth is mine.” (Ex. 19:5)
He’s not just Israel’s God. He owns the whole earth—and chooses Israel not because they own Him, but because He owns all and chooses.
3. Deuteronomy and the Shema: Bold Monotheistic Claim
“Hear, O Israel: The Lord our God, the Lord is one.” (Deut. 6:4)
This declaration is revolutionary. In a world of “many gods for many peoples,” this is a theological mic drop. He is not one among many—He is One. Period.
And just a bit earlier:
“To you it was shown, that you might know that the Lord is God; there is no other besides Him.” (Deut. 4:35)
Now that’s no longer a power competition. That’s a metaphysical declaration.
🌍 Declarations to the Nations: Words and Wonders
4. Conquest and the Witness of the Nations
Rahab in Jericho already got the memo:
“For the Lord your God, He is God in heaven above and on earth beneath.” (Josh. 2:11)
Whoa. That’s not local gossip. That’s cosmic monotheism leaking into Canaanite awareness. Rahab switches allegiance based on this.
5. Elijah on Mount Carmel (1 Kings 18)
This was more than a showdown—it was a theological moment. The people say:
“The Lord, He is God! The Lord, He is God!” (1 Kings 18:39)
That confession doesn’t say, “He’s stronger than Baal.” It declares Baal is nothing, and YHWH is everything.
6. Isaiah’s Thunder: The Global Claim
This is where the full monotheistic weight crashes down like thunder:
“I am the Lord, and there is no other; besides Me there is no God.” (Isa. 45:5)
Isaiah 40–48 is saturated with monotheistic declarations. God mocks idols, proclaims His authorship of history, and declares:
“Before Me there was no god formed, nor shall there be after Me. I, even I, am the Lord, and besides Me there is no Savior.” (Isa. 43:10–11)
He’s not just Israel’s God anymore. He’s the only God there ever was and ever will be.
7. Daniel in Exile: God of Heaven Before Kings
In Babylon, God reveals Himself to Nebuchadnezzar through dreams, judgments, and miracles. And even this pagan king finally says:
“His dominion is an everlasting dominion, and His kingdom endures from generation to generation… He does according to His will in the host of heaven and among the inhabitants of earth.” (Dan. 4:34–35)
The King of Babylon just acknowledged the true Sovereign of the universe.
8. Jesus: The Final Word
And then comes Jesus—God not only revealed but embodied. The Gospel of John begins with:
“In the beginning was the Word… and the Word was God… and the Word became flesh.” (John 1)
And in John 17:3, Jesus defines eternal life itself:
“That they may know You, the only true God, and Jesus Christ whom You have sent.”
In Jesus, the God of Israel is revealed to be the God of all, and the veil is finally torn.
✨ Summary: When Did God Declare Himself the One True God?
- Verbally: As early as the Exodus, but loud and clear in Deuteronomy and Isaiah.
- Publicly (to the nations): Through Egypt, Jericho, Babylon, and ultimately Rome.
- Permanently: Through Jesus, crucified and risen, declared to be the Son of God with power (Rom. 1:4).
If anyone ever thought He was just “Israel’s God,” history, prophecy, and resurrection declare otherwise: He is the One True God, and there is no other.
