Most people have heard of "Armageddon" (the final Biblical battle, not the Bruce Willis movie...although it is also good), but few realize that it's over before it starts.  In one line, John describes the battle lines being set, in the next, Jesus is standing victorious...because nothing can stand against Jesus.  With that in mind, we should love each other, treat each other with respect, and show the truth of that victory each day.
