1 Corinthians 2:2-5.And I, brethren, when I came to you, did not
come with excellence of speech or of wisdom declaring to you the testimony[a] 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[b] 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.
