God in the show is extremely subtle yet omnipresent in everything. Everyone accepts it as a matter of fact, yet as a character, God rarely shows up except to tip the scales one direction or the other. He communicates entirely through prophets and signs that aren't too overt and aren't too subtle. The one episode where satan showed up was interesting too since she clearly has the power to rain down curses and make deals with the humans too.

The writing never quite reaches the point where they could adequately explore these themes though. Definitely too high concept for network television writing constraints.

Not that there are actual writing constraints besides content rules, but network TV just almost always feels like it's been tied down to be Basic AF.
