12 What we have received is not the spirit of the world, but the Spirit who is from God, so that we may understand what God has freely given us. 13 This is what we speak, not in words taught us by human wisdom but in words taught by the Spirit, explaining spiritual realities with Spirit-taught words.[a] 14 The person without the Spirit does not accept the things that come from the Spirit of God but considers them foolishness, and cannot understand them because they are discerned only through the Spirit. 15 The person with the Spirit makes judgments about all things, but such a person is not subject to merely human judgments, 16 for,
“Who has known the mind of the Lord
so as to instruct him?”[b]
But we have the mind of Christ.
Wise men speak because they have something to say; Fools because they have to say something.
