John 6:51-58
6:51 "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."
6:52 The Jews then disputed among themselves, saying, "How can this man give us his flesh to eat?"
6:53 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.
6:54 Those who eat my flesh and drink my blood have eternal life, and I will raise them up on the last day;
6:55 for my flesh is true food and my blood is true drink.
6:56 Those who eat my flesh and drink my blood abide in me, and I in them.
6:57 Just as the living Father sent me, and I live because of the Father, so whoever eats me will live because of me.
6:58 This is the bread that came down from heaven, not like that which your ancestors ate, and they died. But the one who eats this bread will live forever."
