1 Corinthians 2:1-5

When I came to you, brothers, I didn’t come with excellence of speech or of wisdom, proclaiming to you the testimony of God. For I determined not to know anything among you except Jesus Christ and him crucified. I was with you in weakness, in fear, and in much trembling. My speech and my preaching were not in persuasive words of human wisdom, but in demonstration of the Spirit and of power, that your faith wouldn’t stand in the wisdom of men, but in the power of God.
