1 Corinthians 2:6-13

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. 8None of the rulers of this age understood it. For if they had, they would not have crucified the Lord of glory. 9Rather, as it is written:

10But God has revealed it to us by the Spirit.

The Spirit searches all things, even the deep things of God. 11For who among men knows the thoughts of man except his own spirit within him? So too, no one knows the thoughts of God except the Spirit of God. 12We have not received the spirit of the world, but the Spirit who is from God, that we may understand what God has freely given us. 13And this is what we speak, not in words taught us by human wisdom, but in words taught by the Spirit, expressing spiritual truths in spiritual words.3
