John 6:60-66

6:60 Then many of his disciples, when they heard these things, said, “This is a difficult saying! Who can understand it?” 6:61 When Jesus was aware that his disciples were complaining about this, he said to them, “Does this cause you to be offended? 6:62 Then what if you see the Son of Man ascending where he was before? 6:63 The Spirit is the one who gives life; human nature is of no help! The words that I have spoken to you are spirit and are life. 6:64 But there are some of you who do not believe.” (For Jesus had already known from the beginning who those were who did not believe, and who it was who would betray him.) 6:65 So Jesus added, “Because of this I told you that no one can come to me unless the Father has allowed him to come.”

Peter’s Confession

6:66 After this many of his disciples quit following him and did not accompany him any longer.
