1 Corinthians 2:1-3

My brothers and sisters, when I first came to proclaim to you the secrets of God, I refused to come as an expert, trying to impress you with my eloquent speech and lofty wisdom. For while I was with you I was determined to be consumed with one topic—Jesus, the crucified Messiah. I stood before you feeling inadequate, filled with reverence for God, and trembling under the sense of the importance of my words.
