You would have to have lightning handed by God to your server to have a total power failure without proper shutdown in the above scenario.
Do you live somewhere without thunderstorms? This is a regular event in this part of the world during the summer. It happened to me once this year and once last; lost count for previous ones. In both of the recent cases it's believed the servers were burned from the Ethernet side because somewhere in the network was a poor switch that wasn't isolated well enough from the grid when the building was hit. Lightning is tricky that way; cable TV and satellite wiring are also weak links that way.
I didn't feel too bad about last year's because the building next door burned to the ground after being hit within a few seconds of mine, so the fact that I had some server repair didn't seem like too much of a hardship in comparison. The system was down until the fire department had put out the blaze and I was allowed back into the building though. Good thing my cell phone works in the server room; that phone call asking "are you aware the building is being evacuated?" is always a fun one.
I'm not saying God hates you as much as me, because the fact that you've made this statement says it's clearly not the case, just that a plan presuming he's your buddy is a bad one. The way you're characterizing this risk reminds me of when people quote the odds that they'll lose two disks within seconds of one another in a disk array as if it's impossible, something else which of course has also happened to me many times during my career.
