Would an apparently impotent god that requires its believers to do all the messy enforcement and killings be worth worshiping?
I mean, forget a god that’s merely finitely powerful, but will smite you in a timely manner for not stroking its ego, and does useful things like make sure it rains on the crops like clockwork. That’s an easy answer. Worship or get smitten and/or starve.
A god that appears never to do anything at all, with believers that go out and do that smiting, that’s a whole other story. I mean, sure, give lip-service to it so the dolts who believe in it don’t burn you at the stake, but there’s no need to believe in a great straw-man in the sky.
