"One of the hardest, thorniest and most difficult things we humans are ever called upon to do is to respond to evil with kindness, and to forgive the unforgivable. We love to read stories about people who've responded to hatred with love, but when that very thing is demanded of us personally, our default seems to be anger, angst, depression, righteousness, hatred, etc. Yet study after study shows that one of the keys to longevity and good health is to develop a habit of gratitude and let go of past hurts.Want to live a long, happy life? Forgive the unforgivable. It really is the kindest thing you can do for yourself. Your enemy may not deserve to be forgiven for all the pain and sadness and suffering purposefully inflicted on your life, but you deserve to be free of this evil. As Ann Landers often said, "hate is like an acid. It destroys the vessel in which it is stored."
