Can someone forgive a tornado if it destroyed his home?
Forgiveness is toward people who have been unfair. Can a tornado be unfair? No, because a tornado has no intentions to do evil. One can work on acceptance of what happened, but it would be a distortion of forgiveness if you encouraged someone to forgive an inanimate object. A goal of forgiveness, not always possible, is to enter back into a loving or respectful relationship with that person. One cannot ever enter into a loving relationship with a tornado.
