1 Corinthians 1:17-18
1 Corinthians 1: 17 to 18
17 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.
18 For the preaching of the cross is to them that perish foolishness; but to us which are saved it is the power of God.
