Love prospers when a fault is forgiven, but dwelling on it separates close friends. (Proverbs 17:9 NLT)
Too many people “dwell on” things from the past that can never be changed. They’ll throw away lifetime friendships while nursing their bitterness over a hurt suffered months or years ago. You will never have deep, loving relationships if you don’t learn to forgive. Everybody will ultimately disappoint you in some way, but it's important not to hold onto those grievances. If you do, you may end up isolating yourself to such a degree that you'll be the only friend you have.
