1 Corinthians 2:3-6

2:3 And I was with you in weakness and in fear and with much trembling. 2:4 My conversation and my preaching were not with persuasive words of wisdom, but with a demonstration of the Spirit and of power, 2:5 so that your faith would not be based on human wisdom but on the power of God.

Wisdom from God

2:6 Now we do speak wisdom among the mature, but not a wisdom of this age or of the rulers of this age, who are perishing.

1 Corinthians 2:13

2:13 And we speak about these things, not with words taught us by human wisdom, but with those taught by the Spirit, explaining spiritual things to spiritual people.
