John 6:59-63

⁵⁹These things he said in a synagogue, while teaching in Capernaum.

⁶⁰Many therefore of his disciples, when they heard this, said, This teaching is hard; who can listen to it?

⁶¹Jesus therefore knew within himself that his disciples were murmuring about this, and said to them, Doth this offend you?

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

⁶³It is the spirit which maketh alive; the flesh profiteth nothing. The words which I have spoken to you are spirit, and are life.
