I think the perception is that we forgive those who trespass against us because then our trespasses may be forgiven. We are acknowledging that we ourselves are not perfect so in no position to throw stones at anybody else. However there is a more immediate reward in the here and now. Forgive those who have trespassed against you and suddenly they have no power over you. They could dominate your life with thoughts of injury and revenge and suddenly the school bully who beat you up twenty years ago and has doubtless forgotten the whole incident - suddenly he has no more power to hurt you. What do you think ? Or is this the wrong forum?
