1 Corinthians 1:18, 23-25

For the preaching of the cross is to them that perish foolishness; but unto us which are saved it is the power of God.

but we preach Christ crucified, unto the Jews a stumblingblock, and unto the Greeks foolishness; but unto them which are called, both Jews and Greeks, Christ the power of God, and the wisdom of God. Because the foolishness of God is wiser than men; and the weakness of God is stronger than men.
