And I, [when I] came to you, brothers, did not come with superiority of speech or of wisdom, proclaiming to you the testimony of God.
For I decided not to know anything among you except Jesus Christ and him crucified.
And I came to you in weakness and in fear and with much trembling,
and my speech and my preaching [were] not with the persuasiveness of wisdom, but with a demonstration of the Spirit and power,
in order that your faith would not be in the wisdom of men, but in the power of God.
Now we do speak wisdom among the mature, but wisdom not of this age or of the rulers of this age, who are perishing,
but we speak the hidden wisdom of God in a mystery, which God predestined before the ages for our glory,
which none of the rulers of this age knew. For if they had known [it], they would not have crucified the Lord of glory.
But just as it is written, "[Things] which eye has not seen and ear has not heard, and have not entered into the heart of man, all that God has prepared for those who love him."
For to us God has revealed [them] through the Spirit. For the Spirit searches all [things], even the depths of God.
For who among men knows the things of a man, except the spirit of the man that [is] in him? Thus also no one knows the things of God except the Spirit of God.
Now we have received not the spirit of the world, but the Spirit who [is] from God, in order that we may know the things freely given to us by God,
[things] which we also speak, not in words taught by human wisdom, but in [words] taught by the Spirit, explaining spiritual [things] to spiritual [people].
But the natural man does not accept the things of the Spirit of God, for they are foolishness to him, and he is not able to understand [them], because they are spiritually discerned.
Now the spiritual [person] discerns all [things], but he himself is judged by no one.
"For who has known the mind of the Lord; who has advised him?" But we have the mind of Christ.
