Unforgiveness is harmful to the soul of the person refusing to forgive. It is said that being unforgiving is like drinking poison and expecting the other person to die. Do you realize that most times unforgiveness is just because someone doesn't trust that God is in control? They want to be sure that the person "pays" for the pain they've caused, or are causing. They, essentially, do not believe that God loves them enough to handle it appropriately. Yet, how often are we, ourselves, forgiven of things that others would never release us from? Too often to count.
