Ultimately, preaching accomplishes its spiritual purposes not because of the skills or the wisdom of a preacher but because of the power of the Scripture proclaimed (1 Cor. 2:4–5).
1 Cor. 2:4-5: (4) and my speech and my message were not in plausible words of wisdom, but in demonstration of the Spirit and of power, (5) so that your faith might not rest in the wisdom of men but in the power of God.
