1 Corinthians 1:17, 21

For Christ did not send me [as an apostle] to baptize, but [commissioned and empowered me] to preach the good news [of salvation]—not with clever and eloquent speech [as an orator], so that the cross of Christ would not be made ineffective [deprived of its saving power].

For since the world through all its [earthly] wisdom failed to recognize God, God in His wisdom was well-pleased through the foolishness of the message preached [regarding salvation] to save those who believe [in Christ and welcome Him as Savior].
