Forgiveness is the mental, emotional and/or spiritual process of ceasing to feel resentment or anger against another person for a perceived offense, difference or mistake, or ceasing to demand punishment or restitution.
Since the Church's very existence is formed by God's forgiveness it operates as a people of forgiveness, forgiven and forgiving, inextricably tied to peacemaking and justice.
Peter came to Jesus and asked, 'Lord, how many times shall I forgive my brother when he sins against me? Up to seven times?' Jesus answered, 'I tell you, not seven times, but seventy-seven times (or seventy times seven).'" (Matthew 18:21-22)
Keeping an unforgiving attitude causes loss of hair, wrinkles of skin, much earlier signs of high blood pressure, heart attacks, strokes, loss of sex drive, incontinence, irritable bowel syndrome, Dementia.
Being unforgiving is prideful, and just like bad karma, the same thing can happen with being unforgiving. Being unforgiving is what children do, and that is why they need to taught how to forgive. When adults do it, its just plain ignorance and fear to keep putting wood under the fire. A person that can forgive, is a person that is more valuable, has more taste, class, and is just plain cool to be around.
