But for some of us, forgiveness is not a prerequisite to peace. Just because I don't forgive the molester, doesn't mean I am burdened with anger.
The molester would have no bearing on my personal peace at all. that is under my control. For my child, my peace would come from letting the molester have no power over my happiness.
Absolutely, forgiveness is not a prerequisite to peace. However, once one experiences an absolutely unbearable amount of pain, one may reach the final realization that the way back to a sense of personal peace is through letting go of all the anger in one's heart.
Again, forgiveness is not something which is done for the offender; it has nothing to do with them. It is something which is done to restore one's own sense of peace and happiness.
