1 Corinthians 1:18, 23-25

For the word of the cross is foolishness to those who are perishing, but to us who are being saved it is the power of God.

but we preach Christ crucified, to Jews a stumbling block and to Gentiles foolishness, but to those who are the 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.
