1 Corinthians 2:4-7

4My speech and my preaching were not with persuasive words of wisdom but with a demonstration of the Spirit’s power,

5so that your faith might not be based on human wisdom but on God’s power.

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

7On the contrary, we speak God’s hidden wisdom in a mystery, a wisdom God predestined before the ages for our glory.
