Do not gloat when your enemy falls; when he stumbles, do not let your heart rejoice, or the Lord will see and disapprove and turn His wrath away from him.
Wow, how hard is it to obey this scripture?! I can only speak for myself, but I find satisfaction when someone "gets what they deserve." Of course, "what they deserve" is my opinion, from my sinful, judgemental viewpoint. I certainly found this scripture personally convicting and will try to work on changing my tone toward my enemies.
