John 13:19

John 13:19. From henceforth I tell you before it come to pass, that when it is come to pass, ye may believe that I am. These words can hardly mean that Jesus would henceforward tell them events that were to happen in order that, when the events did happen, they might see that He had been a true prophet and might have their faith confirmed. He is here dealing with them as with persons who are to be sent forth to do His work in the world; and it is as if He would say, ‘Because the moment of your work is come I put you in possession of what is to happen, I make you anticipate and foresee it, I give you the same knowledge of it that I have myself, in order that, when suffering comes, you may not only not lose faith by the shock, but may be strengthened in your progress towards a deeper and truer faith. My ever present knowledge corresponds to my ever present Divine existence, to the fact that I am (comp. on John 8:24). Your knowledge shall be to you a proof that it is indeed One who can say “I am” that is in you.' It is not so much of faith in Him as the Messiah that Jesus speaks: it is of faith in the Divine in Him, bestowed through Him upon themselves.
