John 6:33, 35, 51, 53-56

For the bread of God is that which comes down out of heaven, and gives life to the world.”

Jesus said to them, “I am the bread of life; he who comes to Me will not hunger, and he who believes in Me will never thirst.

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

So Jesus said to them, “Truly, truly, I say to you, unless you eat the flesh of the Son of Man and drink His blood, you have no life in yourselves. He who eats My flesh and drinks My blood has eternal life, and I will raise him up on the last day. For My flesh is true food, and My blood is true drink. He who eats My flesh and drinks My blood abides in Me, and I in him.
