Yep. The OT makes it clear he's in competition with other gods, though he claims to be the most powerful and worthy of worship.

I've always liked the idea in American Gods. That is, gods come and go, wax and wane in power according to the number of worshippers. Friend and I were stoned and he brought this up. Thought I was the only one! This was about 2 years after the book, but we didn't know the idea existed.

Fun to think about and makes sense of why god is always so desperate for converts.
