1 Corinthians 2:3 I was with you in weakness and in fear and in much trembling,
4 and my message and my preaching were not in persuasive words of wisdom, but in demonstration of the Spirit and of power,
2 Cor. 11:6 “But even if I am unskilled in speech”
2 Corinthians 11:19 For you, being so wise, tolerate the foolish gladly.
20 For you tolerate it if anyone enslaves you, anyone devours you, anyone takes advantage of you, anyone exalts himself, anyone hits you in the face.
This is the type of leadership and preaching that was tolerate and even applauded in Paul's day. The speaker would make a seen on stage, even abuse the listeners. He would display his power and authority by even going so far as to smack his audience.
What's more, is that in our day, we often value speakers who exalt themselves. We, as evangelicals often flock to those who can attract large crowds. Those who have the most reputable ministries. We love a speaker who has made something for himself. Sure we pause for faux humility "God has blessed my church with such growth" but then we continue right on through with self-exaltation. Preachers publish their methods in books with reproducible 'how-to's'.
Let's be honest, if an apostle Paul came to us and his preaching was characterized by fear and trembling. If he wasn't much to look at and his voice did not resonate with power and personality--we would have no use for such preaching. It would be too weak and lowly for our test. If Paul failed to command the room and drive our attention to him by his style--we, like the Corinthians, would want nothing to do with him.
1 Corinthians 2:1 And when I came to you, brethren, I did not come with superiority of speech or of wisdom, proclaiming to you the testimony of God.2 For I determined to know nothing among you except Jesus Christ, and Him crucified.3 I was with you in weakness and in fear and in much trembling,4 and my message and my preaching were not in persuasive words of wisdom, but in demonstration of the Spirit and of power,5 so that your faith would not rest on the wisdom of men, but on the power of God.
