1 Corinthians 2:13-16

And we speak about these things, not with words taught us by human wisdom but with words taught us by the Spirit. And so we explain spiritual truths to spiritual people. A person who does not have the Spirit does not accept the truths that come from the Spirit of God. That person thinks they are foolish and cannot understand them, because they can only be judged to be true by the Spirit. The spiritual person is able to judge all things, but no one can judge him. The Scripture says: “Who has known the mind of the Lord? Who has been able to teach him?” But we have the mind of Christ.
