64 It is the Spirit who gives life. The flesh does not offer anything of benefit. The words that I have spoken to you are spirit and life.
65 But there are some among you who do not believe." For Jesus knew from the beginning who were unbelieving and which one would betray him.
66 And so he said, "For this reason, I said to you that no one is able to come to me, unless it has been given to him by my Father."
67 After this, many of his disciples went back, and they no longer walked with him.
68 Therefore, Jesus said to the twelve, "Do you also want to go away?"
69 Then Simon Peter answered him: "Lord, to whom would we go? You have the words of eternal life.
70 And we have believed, and we recognize that you are the Christ, the Son of God."
