Maybe you heard about the atheist parents who were trying to pass along their lack of faith to their young son. One night as they were tucking him into bed for the night, the young fellow asked, “Mommy and Daddy, do you think God knows that we don’t believe in him?”
Atheists can try to ignore the existence of God, but the Bible says that God has “…set eternity in the hearts of men…” (Ecclesiastes 3:11). It has been said that there is a God-shaped hole inside of every human being. We have a natural, instinctive longing for something or Someone beyond ourselves. It is foolish to ignore this basic human need. Psalm 14:1 says, “The fool says in his heart, “There is no God…”
By the way, the answer to the question is, “Yes.” God knows that atheists don’t believe in him.
