John 6:53-57

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.

Just as the living Father sent Me, and I live because of the Father, the one who eats Me, he also will live because of Me.
