John 6:61-63

Mace(i) 61 Jesus perceiving in himself, that his disciples murmured at it, said to them, doth this offend you? 62 what if you should see the son of man ascend up where he was before? 63 it is the action of the mind that vivifies, that of the body profits nothing: the words that I have delivered to you, spiritually understood, give life.
