John 6:56-59 New Revised Standard Version (NRSV)
56 Those who eat my flesh and drink my blood abide in me, and I in them. 57 Just as the living Father sent me, and I live because of the Father, so whoever eats me will live because of me. 58 This is the bread that came down from heaven, not like that which your ancestors ate, and they died. But the one who eats this bread will live forever.” 59 He said these things while he was teaching in the synagogue at Capernaum.
