Have you ever felt inclined to throw some stones at someone else? The most helpful definition I've heard of "mercy" is "not giving someone the punishment they deserve". That individual you would like to throw the stone at might very well deserve the punishment. Yet don't you deserve to have a few stones thrown at you? Recognizing our own sinfulness can be the first step in showing mercy toward others. We walk away from the opportunity to give them what they have earned, knowing that we deserve the same punishment ourselves.
