John 6:57-63

57Just as the living Father sent Me and I live because of the Father, so also the one who feeds on Me will live because of Me. 58This is the bread that came down from heaven. Unlike your fathers, who ate the manna and died, the one who eats this bread will live forever.”

59Jesus said this while teaching in the synagogue in Capernaum. 60On hearing it, many of His disciples said, “This is a difficult teaching. Who can accept it?”

61Aware that His disciples were grumbling about this teaching, Jesus asked them, “Does this offend you? 62Then what will happen if you see the Son of Man ascend to where He was before?

63The Spirit gives life; the flesh profits nothing. The words I have spoken to you are spirit and they are life.
