John 6:61-63 English Standard Version Anglicised (ESVUK)
61 But Jesus, knowing in himself that his disciples were grumbling about this, said to them, “Do you take offence at this? 62 Then what if you were to see the Son of Man ascending to where he was before? 63 It is the Spirit who gives life; the flesh is no help at all. The words that I have spoken to you are spirit and life.
