21As for me, brothers, when I came to you, I did not come with superior speech or wisdom in order to proclaim to you the testimony[] of God. 2For I had no intention of knowing anything among you except Jesus Christ, and him crucified. 3I came to you[] in weakness, in fear, and with much trembling. 4My message and my preaching were not marked by persuasive words of human[] wisdom, but by a demonstration of the Spirit and of power, 5so that your faith would not rest on human wisdom, but on God's power. In-Depth Wisdom Is for Spiritual People
6Yet we do speak wisdom among those who are mature, but it is not a wisdom of this world or of the rulers of this world, who are being reduced to nothing. 7Instead we speak God's wisdom that has been hidden in mystery—before the ages, God foreordained that this wisdom would result in our glory. 8None of the rulers of this world knew it. (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 no human mind has conceived—
that is what God has prepared for those who love him.[] 10But God revealed it to us through his[] Spirit. For the Spirit searches all things, even the depths of God. 11Indeed, who among men knows a man's thoughts except the man's spirit within him? So also, no one else knows God's thoughts except God's Spirit. 12What we received is not the spirit of the world, but the Spirit who is from God, so that we might know the blessings freely given to us by God. 13We also speak about these things, not in words taught by human wisdom, but in words taught by the Spirit, combining spiritual truths with spiritual words.[] 14However, an unspiritual person does not accept the truths taught by God's Spirit, because they are foolishness to him, and he cannot understand them, because they are spiritually evaluated. 15But the spiritual person evaluates all things, and he himself is evaluated by no one. 16Indeed, “Who has known the mind of the Lord? Who will instruct him?”[] But we have the mind of Christ.
