John 6:63‭-‬65

It is the Spirit that gives life. The body is of no value for that. But the things I have told you are from the Spirit, so they give life. 

But some of you don’t believe.” (Jesus knew the people who did not believe. He knew this from the beginning. And he knew the one who would hand him over to his enemies.) 

Jesus said, “That is why I said, ‘Anyone the Father does not help to come to me cannot come.’”
