Left to my own devices, I’m a forgiveness denier — I’ll start to think that there are hurts so deep that nothing can heal them. Time alone won’t necessarily do the trick. Our best thinking isn’t enough, or we would all be fine, instead of in our current condition. A lack of forgiveness is like leprosy of the insides, and left untreated, it can take out tissue, equilibrium, soul, sense of self. I have sometimes considered writing a book called All the People I Still Hate: A Christian Perspective., but readers would recoil. Also, getting older means that without meaning to, you accidentally forgive almost everyone — almost — so the book would not be long.
