John 6:57-58

Just as the living Father sent Me, and I live because of the Father, even so the one who feeds on Me [believes in Me, accepts Me as Savior] will also live because of Me. This is the Bread which came down out of heaven. It is not like [the manna that] our fathers ate and they [eventually] died; the one who eats this Bread [believes in Me, accepts Me as Savior] will live forever.”
