These things we also speak, not in words which man’s wisdom teaches but which the Holy Spirit teaches, comparing spiritual things with spiritual. 14 But the natural man does not receive the things of the Spirit of God, for they are foolishness to him; nor can he know them, because they are spiritually discerned. 15 But he who is spiritual judges all things, yet he himself is rightly judged by no one. 16 For “who has known the mind of the Lord that he may instruct Him?” But we have the mind of Christ.
