John 6:66

⁶⁴  But there are some of you that believe not. For Jesus knew from the beginning who they were that believed not, and who should betray him.

⁶⁵  And he said, Therefore said I unto you, that no man can come unto me, except it were given unto him of my Father.

⁶⁶  From that time many of his disciples went back, and walked no more with him.

⁶⁷  Then said Jesus unto the twelve, Will ye also go away?

⁶⁸  Then Simon Peter answered him, Lord, to whom shall we go? thou hast the words of eternal life.
