Man can know the mind of Christ but... can we know the mind of God? What's the difference anyway?
"But a physical man does not receive the things of the spirit of God, for they are foolishness to him; and he cannot get to know [them], because they are examined spiritually. 15 However, the spiritual man examines indeed all things, but he himself is not examined by any man. 16 For “who has come to know the mind of Jehovah, that he may instruct him?” But we do have the mind of Christ." 1Cor2;14
