It is the Spirit Who gives life [He is the Life-giver]; the flesh conveys no benefit whatever [there is no profit in it]. The words (truths) that I have been speaking to you are spirit and life. John 6:63
Your flesh has no benefit in it whatsoever. But don’t despair, the flesh that God gave to Himself, which is Jesus, didn’t either.
And Jesus said to him, Why do you call Me [essentially and perfectly morally] good? There is no one [essentially and perfectly morally] good—except God alone. Mark 10:18
Think of the glory in this Truth, if the flesh of God wasn’t good, you don’t ever have to worry about yours being good enough. The weakness of your flesh in no way limits your Father’s ability of using you. Just as the weakness of Jesus’ flesh didn’t limit God from using Him.
We know that our old (unrenewed) self was nailed to the cross with Him in order that [our] body [which is the instrument] of sin might be made ineffective and inactive for evil, that we might no longer be the slaves of sin. Romans 6:6
I have been crucified with Christ [in Him I have shared His crucifixion]; it is no longer I who live, but Christ (the Messiah) lives in me; and the life I now live in the body I live by faith in (by adherence to and reliance on and complete trust in) the Son of God, Who loved me and gave Himself up for me. Galatians 2:20
