10 God has revealed those things to us by his Spirit. The Spirit searches everything, especially the deep things of God. 11 After all, who knows everything about a person except that person’s own spirit? In the same way, no one has known everything about God except God’s Spirit. 12 Now, we didn’t receive the spirit that belongs to the world. Instead, we received the Spirit who comes from God so that we could know the things which God has freely given us. 13 We don’t speak about these things using teachings that are based on intellectual arguments like people do. Instead, we use the Spirit’s teachings. We explain spiritual things to those who have the Spirit.b

14 A person who isn’t spiritual doesn’t accept the teachings of God’s Spirit. He thinks they’re nonsense. He can’t understand them because a person must be spiritual to evaluate them. 15 Spiritual people evaluate everything but are subject to no one’s evaluation. 

16  “Who has known the mind of the Lord 

so that he can teach him?” 

However, we have the mind of Christ.
