When I came to you, brethren, I did not come with superiority of speech or of wisdom, proclaiming to you the testimony of God. For I determined to know nothing among you except Jesus Christ, and Him crucified. And I was with you in weakness and in fear and in much trembling. And my message and my preaching were not in persuasive words of wisdom, but in demonstration of the Spirit and of power, that your faith should not rest on the wisdom of men, but on the power of God (1 Cor. 2:1–5).
For our exhortation does not come from error or impurity or by way of deceit; but just as we have been approved by God to be entrusted with the gospel, so we speak, not as pleasing men but God, who examines our hearts. For we never came with flattering speech, as you know, nor with a pretext for greed—God is witness—nor did we seek glory from men, either from you or from others, even though as apostles of Christ we might have asserted our authority (1 Thess. 2:3–6).
