We must understand that Forgiveness isn't for the other person, it's for you.  When on the Journey of Forgivenss you must learn to Forgive with grave.  Forgiving with Grace requires you to allow the Spirit of God to do an inner transformation of your heart and soul which will allow you to Forgive in a manner that you yourself don't have the ability to do. Invite the Holy Spirt in with you as you embark on the Journey of Forgiveness. Pray and ask the Lord to cleanse your heart and soul that you may be able to show Grace in Forgiveness.
