I am the bread of life. ...This is the bread that comes down from heaven, so that one may eat of it and not die. I am the living bread that came down from heaven. Whoever eats of this bread will live forever: and the bread that I will give for the life of the world is my flesh. " The Jews then disputed among themselves, saying "How can this man give us his flesh to eat?" So Jesus said to them, "Very truly, I tell you, unless you eat the flesh of the Son of Man and drink his blood, you have no life in you. Those who eat my flesh and drink my blood have eternal life, and I will raise them up on the last day; for my flesh is true food and drink my blood abide in me, and I in them.
