John 6:63-68 Holman Christian Standard Bible (HCSB)
63 The Spirit is the One who gives life. The flesh doesn’t help at all. The words that I have spoken to you are spirit and are life. 64 But there are some among you who don’t believe.” (For Jesus knew from the beginning those who would not[a] believe and the one who would betray Him.) 65 He said, “This is why I told you that no one can come to Me unless it is granted to him by the Father.”
66 From that moment many of His disciples turned back and no longer accompanied Him. 67 Therefore Jesus said to the Twelve, “You don’t want to go away too, do you?”
68 Simon Peter answered, “Lord, who will we go to? You have the words of eternal life.
