Bitterness is resentful cynicism that results in an intense antagonism or hostility toward others. The Bible teaches us to “get rid of all bitterness, rage and anger, brawling and slander, along with every form of malice.” It then goes on to tell us how to deal with such bitterness and its fruits by being “kind and compassionate to one another, forgiving each other, just as in Christ God forgave you” (Ephesians 4:31-32).
