The New Testament’s appeal to people for a new way of relating to one another, a way of kindness, a way that accepts the fact of anger but refuses to allow it to dictate the terms of engagement, is based four-square on the achievement of Jesus. His death has accomplished our forgiveness; very well, we must then pass that on to one another. We must become, must be known as, the people who don’t hold grudges, who don’t sulk. We must be the people who know how to say ‘Sorry’, and who know what to do when other people say it to us. It is remarkable, once more, how difficult this still seems, considering how much time the Christian church has had to think about it and how much energy has been spent on expounding the New Testament where it is all so clear. Perhaps it is because we have tried, if at all, to do it as though it were just a matter of obeying an artificial command—and then, finding it difficult, have stopped trying because nobody else seems to be very good at it either. Perhaps it might be different if we reminded ourselves frequently that we are preparing for life in God’s new world, and that the death and resurrection of Jesus, which by baptism constitute our own new identity, offer us both the motivation and the energy to try again in a new way.
