Anchoring verses

Isaiah 40:21

“Do you not know? Do you not hear? Has it not been told you from the beginning? Have you not understood since the foundation of the earth?”

Romans 1:20

“For since the creation of the world God’s invisible qualities, His eternal power and divine nature, have been clearly seen, being understood from what has been made, so that men are without excuse.”


Shared testimony of creation

• Isaiah insists that the evidence has been “told … from the beginning.”

• Paul echoes that the same evidence has been “clearly seen” since “the creation of the world.”

• Both writers affirm an unbroken, worldwide witness: creation itself preaches God’s reality so plainly that no one can claim ignorance.


What creation reveals about God

• Eternal power – immense energy and force sustaining galaxies (Psalm 19:1–2; Hebrews 11:3).

• Divine nature – intelligence, artistry, order, and beauty (Job 38–39).

• Faithfulness – predictable seasons, sunrise after sunrise (Genesis 8:22; Acts 14:17).

• Care for life – ecosystems balanced to provide food, water, and habitat (Job 12:7-10; Matthew 6:26).

• Sovereign authority – nothing exists apart from His command (Colossians 1:16-17).


Why ignorance is inexcusable

• The witness is universal: every person everywhere experiences sky, land, and sea.

• The message is continuous: day and night “pour forth speech” (Psalm 19:2).

• The facts are plain: design points to a Designer (Hebrews 3:4).

• God has reinforced the visual sermon with the written Word, ensuring clarity for any who will listen (2 Peter 1:19).


Living in the light of this revelation

• Respond with worship – acknowledge His greatness whenever you step outdoors.

• Cultivate gratitude – thank Him for sunlight, rainfall, and the very breath in your lungs.

• Practice stewardship – care for the world He entrusted to humanity (Genesis 2:15).

• Bear witness – use observable wonders as natural openings to speak of the Creator (Acts 17:24-27).

• Walk in humility – creation’s magnitude keeps human pride in check (Isaiah 40:22-23).
