John 6:63-65

BRG Bible

⁶³ It is the Spirit that quickeneth; the flesh profiteth nothing: the words that I speak unto you, they are Spirit, and they are life.

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.
