John 6:52-56

Then the Jews began to argue with one another, saying, “How can this Man give us His flesh to eat?”

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.

The one 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.

The one who eats My flesh and drinks My blood remains in Me, and I in him.
