Forgiveness is taking seriously the awfulness of what has happened when you are treated unfairly. Forgiveness is not pretending that things are other than the way they are.
Forgiveness and reconciliation are not just ethereal, spiritual, other-worldly activities. They have to do with the real world. They are realpolitik, because in a very real sense, without forgiveness, there is no future.
Without forgiveness, there's no future.
Forgiveness is an absolute necessity for continued human existence.
Forgiveness says you are given another chance to make a new beginning.
