John 6:51, 53-57, 63

I [Myself] am this Living Bread that came down from heaven. If anyone eats of this Bread, he will live forever; and also the Bread that I shall give for the life of the world is My flesh (body). And Jesus said to them, I assure you, most solemnly I tell you, you cannot have any life in you unless you eat the flesh of the Son of Man and drink His blood [unless you appropriate His life and the saving merit of His blood]. He who feeds on My flesh and drinks My blood has (possesses now) eternal life, and I will raise him up [from the dead] on the last day. For My flesh is true and genuine food, and My blood is true and genuine drink. He who feeds on My flesh and drinks My blood dwells continually in Me, and I [in like manner dwell continually] in him. Just as the living Father sent Me and I live by (through, because of) the Father, even so whoever continues to feed on Me [whoever takes Me for his food and is nourished by Me] shall [in his turn] live through and because of Me. 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.
