"[John] 6:63 Spirit...flesh...words. When Jesus has ascended where He was before, He will bestow the Spirit on those who believe in Him (7:39). The Spirit will lead those who believe into all truth (16:13); He will enable the believer to apprehend that the flesh of Jesus, which in itself is of no more avail than any human flesh, is the sacrifice of the Lamb of God, given for the life of the world (6:51). The Spirit will recall and confirm in the believer the words of Jesus which gave His flesh this significance and power (14:26); thus the Spirit will give life."
