1 Corinthians 1:17-18, 22-23

For Christ didn’t send me to baptize, but to preach the Good News—and not with clever speech, for fear that the cross of Christ would lose its power. The message of the cross is foolish to those who are headed for destruction! But we who are being saved know it is the very power of God.

It is foolish to the Jews, who ask for signs from heaven. And it is foolish to the Greeks, who seek human wisdom. So when we preach that Christ was crucified, the Jews are offended and the Gentiles say it’s all nonsense.
