John 6:63-65

63It is the Spirit that gives you life. People cannot do that. The words that I have spoken to you come from the Spirit. They give you life.

64But some of you do not believe my message.’ Jesus had known from the beginning which of them would not believe in him. Also, he had always known who would sell him to his enemies.

65Then Jesus said to them, ‘That is why I told you that only the Father can bring people to me. Nobody can come to me unless the Father makes them able to come.’
