John 6:63-65

Revised Standard Version Catholic Edition

⁶³ It is the spirit that gives life, the flesh is of no avail; the words that I have spoken to you are spirit and life. ⁶⁴ But there are some of you that do not believe.” For Jesus knew from the first who those were that did not believe, and who it was that should betray him. ⁶⁵ And he said, “This is why I told you that no one can come to me unless it is granted him by the Father.”
