The way I forgive you is the way God has forgiven me. The reason why forgiveness doesn't come very easily is because it dosen't't come very naturally. It means to let go. There is only one cure for the cancer of bitterness and that is the cure of Forgiveness. Forgiveness is giving up my right to hurt you for hurting me.
True forgiveness means no strings attached and no conditions.
Forgiveness must be free, full, and final. If you are his child God has forgiven all sins. When God forgives God forgets. Bitterness is like a cancer you must remove all of it to heal. You know some people might think that when you become a Christian and take a stand for Jesus Christ and be the witness that God wants you to be that everybody will like you.
