When I came to you proclaiming the mystery of God, I did not come with sublimity of words or of wisdom.  For I resolved to know nothing while I was with you except Jesus Christ, and him crucified.  I came to you in weakness and fear and much trembling, and my message and my proclamation were not with persuasive words of wisdom, but with a demonstration of spirit and power, so that your faith might rest not on human wisdom but on the power of God.

I Corinthians 2:1-5
