1 Corinthians 2:1-5

Brothers and sisters, when I came to you I didn't try to impress you with wonderful words or great wisdom when I told you what God had to say to you. I decided that while I was with you I didn't want to concentrate on anything except Jesus Christ, and that he was crucified. I came to you in weakness, fearful and trembling. I didn't speak to you with persuasive words of wisdom to convince you. I just explained it all to you through the evidence and power of the Spirit. That way your trust in God wouldn't rely on human wisdom but on the power of God.
