1 Corinthians 2:1,3-4 (NLT)
When I first came to you, dear brothers and sisters, I didn't use lofty words and impressive wisdom to tell you God's secret plan.... [3] I came to you in weakness-timid and trembling. [4] And my message and my preaching were very plain. Rather than using clever and persuasive speeches, I relied only on the power of the Holy Spirit.

- Paul would not have much of a career as a tele-evangelist if he were alive today!
