The intellect of a man is a gift from God; but no matter how great it may be, it must in all things be found subservient to the mind of Christ: which mind is made known only by the Spirit through the right operation of His Body.
For who (individually) has understood the mind of the Lord, so as to instruct Him? But WE (the Body) have the mind of Christ.
1 Corinthians 2:16 (ESV)
…so that through the church the manifold wisdom of God might NOW be made known to the rulers and authorities in the heavenly places.
Ephesians 3:10 (ESV)
Where the Body is at war with its own members, the mind of Christ is not understood by them; for they each serve their own interests. Nature itself displays this to us.
To know the mind of Christ, one must first be mindful of whom He knows.
