The Farewell Command (John 13:33-35)

13:33-35 “Little children, I am still going to be with you for a little while. You will search for me; and, as I said to the Jews, so now I say to you too: ‘You cannot go where I am going.’ I give you a new commandment, that you love one another; that you too love one another, as I have loved you; it is by this that all will know that you are my disciples—if you have love amongst each other.”

Jesus was laying down his farewell commandment to his disciples. The time was short; if they were ever to hear his voice they must hear it now. He was going on a journey on which none might accompany him; he was taking a road that he had to walk alone; and before he went, he gave them the commandment that they must love one another as he had loved them. What does this mean for us, and for our relationships with our fellow-men? How did Jesus love his disciples?
(i) He loved his disciples selflessly. Even in the noblest human love there remains some element of self. We so often think—maybe unconsciously—of what we are to get. We think of the happiness we will receive, or of the loneliness we will suffer if love fails or is denied. So often we are thinking: What will this love do for me? So often at the back of things it is our happiness that we are seeking. But Jesus never thought of himself. His one desire was to give himself and all he had for those he loved.
(ii) Jesus loved his disciples sacrificially. There was no limit to what his love would give or to where it would go. No demand that could be made upon it was too much. If love meant the Cross, Jesus was prepared to go there. Sometimes we make the mistake of thinking that love is meant to give us happiness. So in the end it does, but love may well bring pain and demand a cross.
(iii) Jesus loved his disciples understandingly. He knew his disciples through and through. We never really know people until we have lived with them. When we are meeting them only occasionally, we see them at their best. It is when we live with them that we find out their moods and their irritabilities and their weaknesses. Jesus had lived with his disciples day in and day out for many months and knew all that was to be known about them—and he still loved them. Sometimes we say that love is blind. That is not so, for the love that is blind can end in nothing but bleak and utter disillusionment. Real love is open-eyed. It loves, not what it imagines a man to be, but what he is. The heart of Jesus is big enough to love us as we are.
(iv) Jesus loved his disciples forgivingly. Their leader was to deny him. They were all to forsake him in his hour of need. They never, in the days of his flesh, really understood him. They were blind and insensitive, slow to learn, and lacking in understanding. In the end they were craven cowards. But Jesus held nothing against them; there was no failure which he could not forgive. The love which has not learned to forgive cannot do anything else but shrivel and die. We are poor creatures, and there is a kind of fate in things which makes us hurt most of all those who love us best. For that very reason all enduring love must be built on forgiveness, for without forgiveness it is bound to die.
