Hi James,

John 6:66 From that time many of his disciples went back, and walked no more with him.

What were the words from that particular time and moment that were said, that caused them to walk away?

Hint the verse 65, was a summary of the whole chapter six discourse, the word "therefore" is the cue to the summary , it points back to the parable eat flesh, drink blood, it has to do with God having mercy on whom He wills to have mercy and hardening the ones that walked away.

Joh 6:65 And he said, Therefore said I unto you, that no man can come unto me, except it were given unto him of my Father.

It was from that verse that the disciples no longer walked with Christ.
