Paul the apostle repeatedly writes in his first letter to the Corinthians:
For Christ did not send me to baptize, but to preach the gospel — not with wisdom and eloquence, lest the cross of Christ be emptied of its power.
(1 Cor 1:17)
Therefore, as it is written: “Let the one who boasts boast in the Lord.” And so it was with me, brothers and sisters. When I came to you, I did not come with eloquence or human wisdom as I proclaimed to you the testimony about God. For I resolved to know nothing while I was with you except Jesus Christ and him crucified. I came to you in weakness with great fear and trembling. My message and my preaching were not with wise and persuasive words, but with a demonstration of the Spirit’s power, so that your faith might not rest on human wisdom, but on God’s power.
(1 Cor 1:31- 2:5)
If I speak in the tongues of men or of angels, but do not have love, I
am only a resounding gong or a clanging cymbal.
(1 Cor 13:1)
Wisdom and eloquence are good, until they defeat the purpose of the message. When we speak about God, do we glorify Him, or ourselves?
