Why is preaching Christ crucified the only necessary message?

The apostle Paul recognized the necessity of preaching Christ crucified as the only message that can genuinely transform lives. As noted in 1 Corinthians 1:18, 'For the message of the cross is foolishness to those who are perishing, but to us who are being saved it is the power of God.' This authority of the crucifixion lies in that it addresses humanity's ultimate problem: sin and separation from God. Without the cross, there is no salvation, and thus it becomes imperative for Christians to focus solely on Christ's finished work, which provides a comprehensive solution to the curse of sin.
