We are simply not strong enough to see the process through. Forgiveness requires persistence and endurance. It requires physical and emotional strength. It often requires courage we have to dare to confront the other person. Forgiveness requires taking the initiative it's so easy to just let things go on the way they always have been.
Reconciliation requires creativity.
So often, the process gets bogged down, or never gets off square one, because people can't imagine how make a move. Reconciliation means imagining a different world, imagining a world where things aren't impossible. Reconciliation is so difficult, and so expensive, that we usually do everything we can to avoid it. We put up with pain. We put up with anger.
