John 6:47-54
6:47 I tell you the solemn truth, the one who believes has eternal life.
6:48 I am the bread of life.
6:49 Your ancestors ate the manna in the wilderness, and they died.
6:50 This is the bread that has come down from heaven, so that a person may eat from it and not die.
6:51 I am the living bread that came down from heaven. If anyone eats from this bread he will live forever. The bread that I will give for the life of the world is my flesh.”
6:52 Then the Jews who were hostile to Jesus began to argue with one another, “How can this man give us his flesh to eat?”
6:53 Jesus said to them, “I tell you the solemn truth, unless you eat the flesh of the Son of Man and drink his blood, you have no life in yourselves.
6:54 The one who eats my flesh and drinks my blood has eternal life, and I will raise him up on the last day.
