How to respond to christian boss

I work at a very small company and am the only non-christian. It's not a faith based org but the owner is VERY religious and half of the employees are of the same faith. The rest are different factions of that faith. They all know i dont practice but i keep my views to myself.

However, im starting to tire of the “god is guiding us” talk. As an example, i recently made an error but discovered it quickly due to a series of coincidences and managed to fix it before it became a real issue. My boss made mention that “god is always guiding us” and basically said i was led to find this error by god. I REALLY wanted to ask where god’s guidance was when i made the error in the first place.

Anyways, whenever she says something like this I usually just give a “mmmhmmm” or other somewhat neutral and non-commital response. I honestly don’t think there IS a better way I can respond but figured I’d post here in case anyone had suggestions.

And before it’s suggested…there is no HR, it’s an amazing position outside putting up with the religious mumbo jumbo, and I’m not going to quit or report the boss.

P.S. as a reddit refugee who desperately missed the exchristian sub there, i do hope this community can get some more action. Reddit is dead to me, lol.
