John 6:63-65

New Revised Standard Version, Anglicised

⁶³ It is the spirit that gives life; the flesh is useless. The words that I have spoken to you are spirit and life. ⁶⁴ But among you there are some who do not believe.’ For Jesus knew from the first who were the ones that did not believe, and who was the one that would betray him. ⁶⁵ And he said, ‘For this reason I have told you that no one can come to me unless it is granted by the Father.’
