John 6:59-63

⁵⁹These things he said in the synagogue, teaching in Capernaum.

⁶⁰Many therefore of his disciples having heard it said, This word is hard; who can hear it?

⁶¹But Jesus, knowing in himself that his disciples murmur concerning this, said to them, Does this offend you?

⁶²If then ye see the Son of man ascending up where he was before?

⁶³It is the Spirit which quickens, the flesh profits nothing: the words which I have spoken unto you are spirit and are life.
