17 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.

Christ Crucified Is God’s Power and Wisdom

18 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.
19 For it is written: “I will destroy the wisdom of the wise; the intelligence of the intelligent I will frustrate.”a
20 Where is the wise person? Where is the teacher of the law? Where is the philosopher of this age? Has not God made foolish the wisdom of the world?
