And I, brethren, when I came to you, did not come with excellence of speech or of wisdom declaring to you the testimony of God. 2 For I determined not to know anything among you except Jesus Christ and Him crucified. 3 I was with you in weakness, in fear, and in much trembling. 4 And my speech and my preaching were not with persuasive words of human wisdom, but in demonstration of the Spirit and of power, 5 that your faith should not be in the wisdom of men but in the power of God.
— 1 Corinthians 2:1-5.
Paul’s determined resolve in preaching to the Corinthians is never to parade his excellent vocabulary or wisdom, but to concentrate solely on ‘Jesus Christ and Him crucified’. He admits that he feels his great weakness, fear, and trembling and that it is not human wisdom or persuasion that gives power to the message, but the Holy Spirit, as he concentrates on the message of the cross, the true preaching of which always is accompanied by God’s power to save.
