1 Corinthians 1:18, 21, 23

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

For since in the wisdom of God the world through its wisdom did not know him, God was pleased through the foolishness of what was preached to save those who believe.

but we preach Christ crucified: a stumbling block to Jews and foolishness to Gentiles
