Isaiah 40:21: God's rule in creation?
How does Isaiah 40:21 affirm God's sovereignty in creation and history?

Setting Isaiah 40:21 in Context

Isaiah 40 opens a new section of the book, shifting from oracles of judgment to words of comfort for Judah in exile.

• The prophet reminds a discouraged people that the Lord who promises deliverance is the same Lord who created and rules everything. Verse 21 functions as a rhetorical wake-up call.


The Text: Isaiah 40:21

“Do you not know? Have you not heard? Has it not been declared to you from the beginning? Have you not understood since the foundations of the earth?”


Key Phrases That Underscore Sovereignty

• “Do you not know? Have you not heard?”

– Drives home that God’s supremacy is established truth, woven into Israel’s collective memory (Deuteronomy 4:32-35).

• “Declared … from the beginning”

– Points back to Genesis 1:1, the foundational testimony that God alone created.

• “Since the foundations of the earth”

– Stresses that God’s rule predates—and therefore governs—everything that exists (Psalm 90:2).


Creation: God’s Ultimate Credential

Genesis 1:1—“In the beginning God created the heavens and the earth.” Creation is the first evidence of His absolute authority.

Psalm 24:1-2—Because He founded the world, “the earth is the LORD’s.” Ownership flows from authorship.

Colossians 1:16-17—All things were created “through Him and for Him … in Him all things hold together,” underscoring continuous, not just initial, sovereignty.


History: God Directing the Nations

• Isaiah later applies the same logic: “I am God, and there is none like Me … My purpose will be established, and I will accomplish all My good pleasure” (Isaiah 46:9-10).

Acts 17:24-26—Paul echoes Isaiah, declaring that the Creator “determined their appointed times and the boundaries of their lands.”

• The exile itself proves God’s control; He raised up Babylon (Isaiah 10:5-6) and would soon topple it (Isaiah 45:1-4).


Implications for Believers Today

• Confidence: If the Lord called the universe into being, He can handle present crises.

• Perspective: World events—rising powers, cultural shifts—unfold under His plan, not by human chance.

• Worship: Recognizing His creative and historical rule fuels wholehearted praise (Revelation 4:11).

• Obedience: Sovereign authority summons complete trust and submission (Proverbs 3:5-6).
