John 6:59-63

⁵⁹These things said he in the synagogue, as he taught in Capernaum.

⁶⁰Many therefore of his disciples, when they heard this, said, This is a hard saying; who can hear it?

⁶¹But Jesus knowing in himself that his disciples murmured at this, said unto them, Doth this cause you to stumble?

⁶²What then if ye should behold the Son of man ascending where he was before?

⁶³It is the spirit that giveth life; the flesh profiteth nothing: the words that I have spoken unto you are spirit, and are life.
