1 Corinthians 1:17-18 (New Living Translation)
[Christ sent me] 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.
The cross--the very power of God! What a paradox! To the Romans Paul wrote, "For I am not ashamed of the gospel of Jesus the Messiah, for it is the power of God unto salvation to those who believe."
Perhaps sometimes "clever speech" actually obscures the love of Christ.
