John 6:63-66

It is the Spirit that gives life. The flesh doesn’t give life. The words I told you are spirit, and they give life. But some of you don’t believe.” (Jesus knew from the beginning who did not believe and who would turn against him.) Jesus said, “That is the reason I said, ‘If the Father does not bring a person to me, that one cannot come.’ ” After Jesus said this, many of his followers left him and stopped following him.
