60 Many of Jesus' disciples heard him and said, “This is too hard for anyone to understand.”
61 Jesus knew that his disciples were grumbling. So he asked, “Does this bother you?
62 What if you should see the Son of Man go up to heaven where he came from?
63 The Spirit is the one who gives life! Human strength can do nothing. The words that I have spoken to you are from that life-giving Spirit.
64 But some of you refuse to have faith in me.” Jesus said this, because from the beginning he knew who would have faith in him. He also knew which one would betray him.
65 Then Jesus said, “You cannot come to me, unless the Father makes you want to come. That is why I have told these things to all of you.”
66 Because of what Jesus said, many of his disciples turned their backs on him and stopped following him.
