"And war broke out in heaven..." that is perhaps the most chilling verse in the Bible. For if war can break out in heaven, then what hope can we ever have for peace?
The thing about this verse is the timing... did it happen or will it happen? Or both? The Revelation to John isn't clear at all. No surprise there... prophesies and signs are never really clear until we can document them. We blame the Devil for our own original sin, for the seven deadly sins, for evil in general, but what if the Devil has nothing to do with the mess we've made on earth? What if we have nobody to blame but ourselves... our own human incompetence and greed?
Michael and his angels fought against the dragon. Who will fight for us?
It's also no surprise (to me) that Michael is the patron saint of police officers. In their own way, they fight for the ordinary citizen's right to safety and peace. Two in my family are now in that profession. God bless them.
