Isaiah 29:15 on God's omniscience?
What does Isaiah 29:15 reveal about God's omniscience and human deception?

Text of Isaiah 29 : 15

“Woe to those who go deep to hide their plans from the LORD; they do their deeds in darkness and say, ‘Who sees us?’ and ‘Who knows us?’”


Key Observations

• “Woe” signals God’s settled opposition to the conduct described.

• The offenders deliberately “go deep” and “do their deeds in darkness,” portraying intentional secrecy.

• Their questions—“Who sees?” “Who knows?”—assume God is either blind or absent.


God’s Omniscience Highlighted

• The warning presupposes that God, in fact, does see and does know.

Psalm 139 : 1-4—“You discern my thoughts from afar… even before a word is on my tongue, You know it.”

Jeremiah 23 : 24—“Can a man hide in secret places so that I cannot see him?… Do I not fill heaven and earth?”

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

• Isaiah’s “woe” rests on the certainty that God’s knowledge is immediate, exhaustive, and personal.


Human Deception Exposed

• Sinners attempt a double deceit: hiding plans from God and denying His perception.

• Darkness and secrecy are not merely physical; they symbolize spiritual rebellion (John 3 : 19-20).

• By asking “Who sees?” they reveal a willful suppression of truth (Romans 1 : 18).

• Such self-deception breeds further transgression, because people sin more freely when they imagine they will never be found out.


Consequences of Trying to Hide from God

• Immediate: alienation and a hardened heart (Isaiah 6 : 9-10).

• Eventual: exposure—“For nothing is concealed that will not be disclosed” (Luke 12 : 2-3).

• Inevitable judgment—“God will bring every deed into judgment, including every hidden thing” (Ecclesiastes 12 : 14).


Practical Takeaways for Believers

• Live transparently before God; secrecy is futile and corrosive.

• Invite His searching gaze daily (Psalm 139 : 23-24).

• Reject the lie that private sin is harmless; God sees and sin always costs.

• Walk in the light through confession and obedience (1 John 1 : 7-9).
