John 6:60-69

And when many of Jesus’ followers heard these things, it caused a stir. “That’s disgusting!” they said. “How could anybody accept it?” Without anyone telling him, Jesus knew they were outraged and told them, “Are you offended over my teaching? What will you do when you see the Son of Man ascending into the realm from where he came? “The Holy Spirit is the one who gives life, that which is of the natural realm is of no help. The words I speak to you are Spirit and life. But there are still some of you who won’t believe.” In fact, Jesus already knew from the beginning who the skeptics were and who his traitor would be. He went on to say, “This is why I told you that no one embraces me unless the Father has given you to me.” And so from that time on many of the disciples turned their backs on Jesus and refused to be associated with him. So Jesus said to his twelve, “And you—do you also want to leave?” Peter spoke up and said, “But Lord, where would we go? No one but you gives us the revelation of eternal life. We’re fully convinced that you are the Anointed One, the Son of the Living God, and we believe in you!”
