Link Isaiah 40:18 & Exodus 20:4-5 on idols.
Connect Isaiah 40:18 with Exodus 20:4-5 on the prohibition of idols.

The Setting: Two Passages, One Message

Isaiah 40:18: “To whom will you liken God? To what image will you compare Him?”

Exodus 20:4-5: “You shall not make for yourself an idol in the form of anything in the heavens above, on the earth below, or in the waters beneath. You shall not bow down to them or serve them; for I, the LORD your God, am a jealous God…”


God’s Unrivaled Nature in Isaiah 40:18

• The prophet poses two rhetorical questions that expose the absurdity of comparing the infinite Creator to any finite image.

• The verse stands in a chapter emphasizing God’s greatness: He measures the waters in His hand (v. 12) and sits enthroned above the circle of the earth (v. 22).

• The unspoken conclusion: No likeness, statue, or concept can capture who He is.


The Command in Exodus 20:4-5

• “You shall not make… You shall not bow down… or serve them” – three prohibitions that grow progressively stronger.

• The scope is total: heaven, earth, sea—nothing created may be fashioned into a representation of the Creator.

• God calls Himself “jealous,” revealing His zeal to protect His exclusive worth and the covenant relationship with His people.


Key Connections

• Isaiah’s question (“To whom will you liken God?”) answers Exodus’s command (“Do not make an idol”): likeness is impossible; therefore, idolatry is forbidden.

• Both passages stress God’s uniqueness—He alone is God (cf. Deuteronomy 4:35; Isaiah 46:5, 9).

• Exodus gives the legal prohibition; Isaiah supplies the theological rationale.


Why Idolatry Offends God

• It diminishes His glory by shrinking the infinite to the finite (Psalm 115:4-8).

• It redirects worship from Creator to creation (Romans 1:22-23).

• It fractures covenant love: “I… am a jealous God” (Exodus 20:5).

• It blinds hearts to truth, keeping people from knowing the living God (Habakkuk 2:18-20).


New-Testament Echoes

Acts 17:29—Paul repeats Isaiah’s logic: “Since we are God’s offspring, we should not think that the Divine Being is like gold or silver or stone…”

1 John 5:21—“Little children, keep yourselves from idols,” an enduring application for believers after the cross and resurrection.


Living This Truth Today

• Guard the heart from substituting anything—possessions, relationships, status—for devotion to God alone.

• Worship God as He has revealed Himself in Scripture, not as imagination reshapes Him.

• Proclaim His uniqueness in a culture that still crafts idols of success, pleasure, and self.

In both passages, God’s incomparable majesty undergirds the timeless command: no idols—ever.
