John 6:41-58
Then the people began to murmur in disagreement because he had said, “I am the bread that came down from heaven.” They said, “Isn’t this Jesus, the son of Joseph? We know his father and mother. How can he say, ‘I came down from heaven’?”
But Jesus replied, “Stop complaining about what I said. For no one can come to me unless the Father who sent me draws them to me, and at the last day I will raise them up. As it is written in the Scriptures, ‘They will all be taught by God.’ Everyone who listens to the Father and learns from him comes to me. (Not that anyone has ever seen the Father; only I, who was sent from God, have seen him.)
“I tell you the truth, anyone who believes has eternal life. Yes, I am the bread of life! Your ancestors ate manna in the wilderness, but they all died. Anyone who eats the bread from heaven, however, will never die. I am the living bread that came down from heaven. Anyone who eats this bread will live forever; and this bread, which I will offer so the world may live, is my flesh.”
Then the people began arguing with each other about what he meant. “How can this man give us his flesh to eat?” they asked.
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. For my flesh is true food, and my blood is true drink. Anyone who eats my flesh and drinks my blood remains in me, and I in him. I live because of the living Father who sent me; in the same way, anyone who feeds on me will live because of me. 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.”
