1 Corinthians 2:1-16

When I came to you, brothers and sisters, I did not come proclaiming the testimony of God to you with superior speech or wisdom. For I decided to know nothing among you except Jesus Christ and him crucified. And I came to you in weakness and in fear and in much trembling. My speech and my proclamation were made not with persuasive words of wisdom but with a demonstration of the Spirit and of power, so that your faith might rest not on human wisdom but on the power of God.
