John 6:47-52

Verily, verily, I say unto you, He that believeth hath eternal life. I am the bread of life. Your fathers ate the manna in the wilderness, and they died. This is the bread which cometh down out of heaven, that a man may eat thereof, and not die. I am the living bread which came down out of heaven: if any man eat of this bread, he shall live for ever: yea and the bread which I will give is my flesh, for the life of the world. The Jews therefore strove one with another, saying, How can this man give us his flesh to eat?
