John 6:60-65 NASB
Therefore many of His disciples, when they heard this said, “This is a difficult statement; who can listen to it?”
But Jesus, conscious that His disciples grumbled at this, said, “This is a difficult statement; who can listen to it?”
“What then if you see the Son of Men ascending to where He was before?
It is the Spirit who gives life; the flesh profits nothing; the words that I have spoken to you are spirit and are life.
But there are some of you who do not believe.”
For Jesus knew from the beginning who they were who did not believe, and who it was that would betray Him.
And He was saying, “For this reason I shave said to you, that no one can come to Me unless it has been granted him from the Father.”
