John 6:57-63

57As the living Father sent Me, and I live because of the Father, so he who feeds on Me will live because of Me.

58This is the bread which came down from heaven—not as your fathers ate the manna, and are dead. He who eats this bread will live forever.”

59These things He said in the synagogue as He taught in Capernaum.

60Therefore many of His disciples, when they heard this, said, “This is a hard saying; who can understand it?”

61When Jesus knew in Himself that His disciples complained about this, He said to them, “Does this offend you?

62What then if you should see the Son of Man ascend where He was before?

63It is the Spirit who gives life; the flesh profits nothing. The words that I speak to you are spirit, and they are life.
