John 6:66-69

⁶⁶And he said: Therefore did I say to you, that no man can come to me, unless it be given him by my Father.

⁶⁷After this many of his disciples went back; and walked no more with him.

⁶⁸Then Jesus said to the twelve: Will you also go away?

⁶⁹And Simon Peter answered him: Lord, to whom shall we go? thou hast the words of eternal life.
