1 Corinthians 1:20-21

20 gWhere is the one who is wise? Where is the scribe? Where is the debater of this age? hHas not God made foolish the wisdom of the world? 21For since, in the wisdom of God, the world did not know God through wisdom, it pleased God through the folly of what we preach
Or  the folly of preaching
to save those who believe.
