1 Corinthians 2:4-7

4My speech and my preaching were not with persuasive words of wisdom, but in demonstration of the Spirit and of power—

5so that your faith would not be in the wisdom of men but in the power of God.

6We do speak wisdom, however, among those who are mature—but not a wisdom of this age or of the rulers of this age, who are coming to nothing.

7Rather, we speak God’s wisdom in a mystery—a wisdom that has been hidden, which God destined for our glory before the ages.
