1 Corinthians 2
1And when I came to you, brothers, I did not come with superiority of speech or wisdom, announcing to you the testimony of God. 2For I decided to know nothing among you except Jesus Christ, and him crucified. 3And I was with you in weakness and fear and much trembling. 4And my speech and my proclamation were not with wisdom's persuasion, but with a demonstration of the Spirit and power, 5so that your faith might rest not on human wisdom but on God's power.
6Yet we speak wisdom among the mature, but not the wisdom of this age or of the rulers of this age, who are being brought to nothing. 7Rather, we speak God's wisdom in a mystery, the hidden wisdom that God destined beforehand for our glory before the ages. 8None of the rulers of this age has known it, for if they had known it, they would not have crucified the Lord of glory. 9But as it is written, “What no eye has seen and no ear has heard, and what has not entered a human heart—what God has prepared for those who love him.” 10For God revealed these things to us through the Spirit. For the Spirit searches everything, even God's depths. 11For who among people knows a person's affairs except that person's spirit within him? In the same way, no one has known God's affairs except God's Spirit. 12But we received not the spirit of the world but the Spirit who is from God, so that we might know the things freely given to us by God.
13We also speak these things, not in words taught by human wisdom but in words taught by the Spirit, interpreting spiritual things to spiritual people. 14But the natural person does not accept the things of God's Spirit, for they are foolishness to him, and he cannot know them because they are examined spiritually. 15But the spiritual person examines all things, while he himself is examined by no one. 16For “Who has known the Lord's mind, who will instruct him?” But we have Christ's mind.
