JOHN 6:62-65

⁶²What then if ye should behold the Son of man ascending where he was before?

⁶³It is the spirit that quickeneth; the flesh profiteth nothing: the words that I have spoken unto you are spirit, and are life.

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

⁶⁵And he said, For this cause have I said unto you, that no man can come unto me, except it be given unto him of the Father.
