“Sheol and the place of destruction are in front of Jehovah. How much more so the hearts of the sons of mankind!” says a writer of Proverbs.​—Prov. 15:11.

If Jehovah so thoroughly knows the dead, then, how easy it is for Jehovah, the Creator of the human heart, to see all that is in the hearts of mankind now living. Through the prophet Jeremiah, Jehovah stated: “I, Jehovah, am searching the heart, examining the kidneys, even to give to each one according to his ways, according to the fruitage of his dealings.” (Jer. 17:10) The speech, expression and acts of an individual show to a great extent what is in his heart. Even men can see it to a limited degree. How much more so Jehovah!
