1 Corinthians 1:18, 23-24

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.

So when we preach that Christ was crucified, the Jews are offended and the Gentiles say it’s all nonsense. But to those called by God to salvation, both Jews and Gentiles, Christ is the power of God and the wisdom of God.
