John 6:53-54, 58

So Jesus said again, “I tell you the truth, unless you eat the flesh of the Son of Man and drink his blood, you cannot have eternal life within you. But anyone who eats my flesh and drinks my blood has eternal life, and I will raise that person at the last day.

I am the true bread that came down from heaven. Anyone who eats this bread will not die as your ancestors did (even though they ate the manna) but will live forever.”
