Books with God or the Devil

I think I may be asking for something a bit too specific, but I love stories with God or the Devil in them. The various interpretations of these ‘characters’ intrigue me so much, as they seem fantastic for a variety of portrayals, either good, bad, or neutral for either of them.

I am looking for any stories that feature them in some capacity. They do not necessarily need to be main characters, just whatever is occurring is occurring by something they cause. I was reading “Feed the Big” by Elias Witherow and (no deep spoilers) the setting being something involved with God, even in a tertiary sense, is still good to me.

And I am not asking for religious horror, per se; could be that these are that world’s equivalent if that makes sense. In “The Sadist’s Bible” by Nicole Cushion, the ‘God’ in it was the Creator of the world but was far from what was what we know ‘God’ as. Or even in a two-part episode of Doctor Who, where he faces a being that called itself the Beast, and was the basis of every belief in the devil across the universe, or even “The Prince of Darkness” movie by John Carpenter. I am more for the more tradition fallen angel/Lucifer/Satan versions of the Devil but I am fine with different ones.

Hopefully, this is not too particular or too all over the place. And it does not matter if it is long or short, novel or short story, I am fine with any. Thank you for your time.

Quick Add: I have read "Between Two Fires" by Christopher Buehlman and loved it.
