Anonymity and facelessness make it almost impossible for healing to take place. Forgiveness needs the help of God in order to happen. Forgiveness is probably the hardest thing we have to work through as human beings. I would go so far as to say that reconciliation is impossible, without the help and presence and inspiration of the Holy Spirit. 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.
