I am afraid to forgive because it could open up old wounds. Maybe I am better off just living with the pain.
Let us start with an analogy. Suppose you have a torn ligament in your knee and your physician recommends surgery. Suppose further that you are afraid of the surgery because it and the subsequent rehabilitation work will be painful. Would you just live with the knee pain, which could get worse and interfere with your quality of life, or would you go ahead with the surgery? Please notice that you will have pain either way—because of the torn ligament in the knee or because of the surgery and rehabilitation. The latter pain will end. The knee pain from the neglected medical treatment will continue and possibly get worse. Which do you choose?
It is the same with the process of forgiveness. You already have the “old wounds” because of the injustice against you. Forgiveness does not create more “old wounds” but instead introduces new and **temporary pain** because of the surgery-of-the-heart and the forgiveness rehabilitation, which could lead to permanent healing. Thus, I would not let the “old wounds” stand in the way of genuine healing.
