John 6:46-56

46 This does not mean that anyone has seen the Father; he who is from God is the only one who has seen the Father.
47 I am telling you the truth: he who believes has eternal life.
48 I am the bread of life.
49 Your ancestors ate manna in the desert, but they died.
50 But the bread that comes down from heaven is of such a kind that whoever eats it will not die.
51 I am the living bread that came down from heaven. If you eat this bread, you will live forever. The bread that I will give you is my flesh, which I give so that the world may live."
52 This started an angry argument among them. "How can this man give us his flesh to eat?" they asked.
53 Jesus said to them, "I am telling you the truth: if you do not eat the flesh of the Son of Man and drink his blood, you will not have life in yourselves.
54 Those who eat my flesh and drink my blood have eternal life, and I will raise them to life on the last day.
55 For my flesh is the real food; my blood is the real drink.
56 Those who eat my flesh and drink my blood live in me, and I live in them.
