1 Corinthians 1:17-18, 22-23

For Christ did not send me to baptize, but to preach the gospel—not with wisdom and eloquence, lest the cross of Christ be emptied of its power. 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.

Jews demand signs and Greeks look for wisdom, but we preach Christ crucified: a stumbling block to Jews and foolishness to Gentiles
