Is it possible that for some people forgiveness does not “work” in that they find no relief?
When this happens, I recommend: 1) more time in forgiving this person and, if this still is not working, 2) try to see if this person reminds you of someone else in need of your forgiving. For example, a person is having trouble forgiving his wife. His wife has behavioral patterns similar to his mother, whom he has not forgiven. I then recommend that he forgive his mother first. When he then focuses on forgiving his wife, the anger toward his mother is not getting in the way of that forgiving.
