1 Corinthians 2:4-6

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, ¹  but not a wisdom of this age or of the rulers of this age, who are perishing.

[2:6]  ¹ tn In extrabiblical literature this word was applied to an initiate of a mystery religion (BDAG 995 s.v. τέλειος 3, gives numerous examples and states this was a technical term of the mystery religions). It could here refer to those who believed Paul’s message, the mystery of God (v. 1), and so be translated as “those who believe God’s message.”
