In this sermon on Proverbs 15:11, Charles Spurgeon argues that most people are "practical atheists" who live as if God doesn't see them even though they believe He exists, and he demonstrates God's omniscience by showing that if God can see all of death's ancient burial places and every detail of hell's torments, He certainly sees the comparatively small and brief lives of humans. Spurgeon explains that God doesn't just glance at hearts but thoroughly searches them like an officer searching a house with a candle, tests them like a goldsmith trying gold in a furnace, and weighs them like a merchant weighing merchandise—knowing every lust, blasphemy, imagination, device, resolve, and broken promise hidden within. He warns hypocrites that their masks will be torn away at judgment, and urges sinners to stop living as if unseen since God's constant gaze should either terrify them into repentance or (once they turn to Christ) become their comfort rather than their horror.
