John 6:51-56

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

⁵²Then the Jews began to argue with one another, saying, “How can this Man give us His flesh to eat?” ⁵³So 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. ⁵⁴The one who eats My flesh and drinks My blood has eternal life, and I will raise him up on the last day. ⁵⁵For My flesh is true food, and My blood is true drink. ⁵⁶The one who eats My flesh and drinks My blood remains in Me, and I in him.
