1 Corinthians 1:17-18 For Christ sent me not to baptize, but to preach the gospel: not with wisdom of words, lest the cross of Christ should be made of none effect. For the preaching of the cross is to them that perish foolishness; but unto us which are saved it is the power of God.
The preaching of the cross is a shocking message. The Jewel of Heaven -- scourged, beaten, spit upon, beard plucked out, mocked, and stripped naked; was nailed to a cruel cross (tortured) until he died. Thank God that three days later he arose from the grave.
The message of the cross is a simple message. Believe in Jesus and Him alone for salvation. Accept by faith His blood atonement for your sins. Nobody can earn salvation. It's a gift, given by the grace of God. Your sins are forgiven and forever forgotten. You are promised eternal life when you believe.
The cross is God's statement of love to the world - John 15:13.
