Genesis 18:20: God's awareness of sin?
How does Genesis 18:20 demonstrate God's awareness of human sinfulness?

Setting the Scene

Genesis 18 finds Abraham hosting three heavenly visitors.

• In verse 20, one of them—identified in the passage as the LORD—speaks plainly about the moral situation in Sodom and Gomorrah.


Scripture Focus

“Then the LORD said, ‘The outcry against Sodom and Gomorrah is great, and their sin is very grievous.’” (Genesis 18:20)


Immediate Truths We Learn

• God hears an “outcry”—a word implying cries of injustice and suffering rising up to Him.

• He calls the sin of the cities “very grievous,” revealing a precise, measured evaluation.

• By speaking before investigating (vv. 21 ff.), He shows He already knows the situation perfectly.


How the Verse Demonstrates Divine Awareness of Sin

1. Direct Testimony

– God Himself states the facts; no human informs Him.

– His declaration underscores omniscience: He possesses exhaustive knowledge without relying on rumor.

2. Moral Evaluation

– He not only knows acts committed but weighs their severity (“very grievous”).

– The wording confirms He discerns motives, patterns, and impact.

3. Response to Outcry

– “Outcry” suggests victims have suffered. God attends to the oppressed (Exodus 3:7).

– Hearing these cries proves His attentiveness to every human voice (Psalm 34:15).


Echoes in the Wider Canon

Psalm 139:1–4 — “You have searched me, LORD, and You know me… before a word is on my tongue, You know it completely.”

2 Chronicles 16:9 — “For the eyes of the LORD roam to and fro over all the earth…”

Hebrews 4:13 — “Nothing in all creation is hidden from God’s sight.”

Revelation 18:5 — Babylon’s sins “have piled up to heaven, and God has remembered her crimes,” paralleling Genesis 18:20’s language of accumulating guilt.


Why God’s Awareness Matters Today

• Sin is never private; the Lord witnesses every thought, word, and deed.

• Injustice does not go unnoticed; He hears every cry for help.

• Because He sees perfectly, His judgments are always right (Psalm 19:9).

• Awareness invites repentance—just as Abraham interceded, so we turn to God’s mercy in Christ (Acts 17:30).


Living in the Light of His Knowledge

• Walk transparently, knowing the One who sees all also offers forgiveness (1 John 1:9).

• Stand against injustice; the same Lord who heard Sodom’s outcry still hears today.

• Cultivate reverent awe; His perfect knowledge calls for holy living (1 Peter 1:15–16).
