6However, when we are among mature people, we do speak a message of wisdom, but not the wisdom of this world or of the rulers of this world, who are passing off the scene.
11Is there anyone who can understand his own thoughts except his own inner spirit? In the same way, no one can know the thoughts of God except God's Spirit.
12Now, we have not received the spirit of the world but the Spirit who comes from God, so that we can understand the things that were freely given to us by God.
13We don't speak about these things with words taught us by human wisdom, but with words taught by the Spirit, as we explain spiritual things to spiritual people.
14A person who isn't spiritual doesn't accept the things of God's Spirit, for they are nonsense to him. He can't understand them because they are spiritually evaluated.
