In 1 Corinthians 1:18-21, the message of God, foolishness to the perishing, but power of God to the saved.
1 Corinthians 1:18-21
[18]For the message about Christ’s death on the cross is nonsense to those who are being lost; but for us who are being saved it is God’s power.
[19]The scripture says: “I will destroy the wisdom of the wise and set aside the understanding of the scholars.”
[20]So then, where does that leave the wise? or the scholars? or the skilful debaters of this world? God has shown that this world’s wisdom is foolishness!
[21]For God in his wisdom made it impossible for people to know him by means of their own wisdom. Instead, by means of the so-called “foolish” message we preach, God decided to save those who believe.
