John 6:53-54, 58

Jesus said to them, “Very truly I tell you, unless you eat the flesh of the Son of Man and drink his blood, you have no life in you. Whoever eats my flesh and drinks my blood has eternal life, and I will raise them up at the last day.

This is the bread that came down from heaven. Your ancestors ate manna and died, but whoever feeds on this bread will live forever.”
