Forgiveness is not merely a feeling. It is primarily a decision, an act of the will, that God calls you to make, often in spite of your feelings. Forgiveness is always costly, just like it cost God something great, in his Son, to forgive you. It will always cost you something great to forgive someone else. The person who has wronged you is in your debt until you decide to release that debt you've been holding on to. Forgiveness is a costly choice for you, but a choice that always pays the giver rich dividends.
