1 Corinthians 1:17, 21
1 Corinthians 1:17 NASB1995
For Christ did not send me to baptize, but to preach the gospel, not in cleverness of speech, so that the cross of Christ would not be made void.
1 Corinthians 1:21 NASB1995
For since in the wisdom of God the world through its wisdom did not come to know God, God was well-pleased through the foolishness of the message preached to save those who believe.
