John 6:51-54

51I am the living bread which came down from heaven. If anyone eats of this bread, he will live forever; and the bread that I shall give is My flesh, which I shall give for the life of the world.”

52The Jews therefore quarreled among themselves, saying, “How can this Man give us His flesh to eat?”

53Then Jesus said to them, “Most assuredly, I say to you, unless you eat the flesh of the Son of Man and drink His blood, you have no life in you.

54Whoever eats My flesh and drinks My blood has eternal life, and I will raise him up at the last day.
