1 Corinthians 2:4-7

4My message and my preaching were not with persuasive words of wisdom, but with a demonstration of the Spirit’s power, 5so that your faith would not rest on men’s wisdom, but on God’s power.

6Among the mature, however, we speak a message of wisdom—but not the wisdom of this age or of the rulers of this age, who are coming to nothing. 7No, we speak of the mysterious and hidden wisdom of God,1 which He destined for our glory before time began.
