I understand you to an extent; but, it still doesn't make sense. Gods aren't "just spirits". It's a collective term to describe a family of ancestral spirits, environmental, spirits from our heritage/history, and not limited to. God just means object or person of worship. However, if you want to get to the nature of god, then god would be to me spirit, to others creator, and to others consciousnesses. I don't accept these are all the same but the context mirrors each other so much that I don't see how believers can't see the relationship between them.
If god the creator is spirit, who is he a spirit of? What defines him as a creator? There are many supreme gods according to other religions. There are many other creators according to even other religions. However, I notice say in African traditions, they actually define the nature of the creator rather than just saying "he creates" or "he is love" or so have you. The creator is solid and has a personality and literally interacts in and with people. That's spirit. We understand the spirit by our ancestors and environment (and above). It's just a beautiful thing.
I wouldn't say unfortunately, but I don't have scripture to go by and the bible isn't my authority; so, it's hard to understand what you say if you're basing it off the Bible literal rather than your comments and beliefs itself in your words.
In some religions you have a boss or more than one boss and you have many supervisors. Some bosses take roles in certain parts of the day while others in another part. Some are temporary, others are not. However, depending on the company, they work together as a whole.
If you are running your own business, sure, there is one boss and everyone else is below you; however, that's not how I see life. We depend on each other and as a humanity, our reflection of who we are, if there are entities called gods, it would be a reflection of who the gods are.
I just don't understand the "one god" thing. I don't believe in a creator and spirits guide us, they don't create us. God is an object or person of worship; so, spirits is the best term if you wanted to describe god or gods as an entity or entities. However, the spirits I'm talking about, their nature are ancestral, historical, heritage, kin, and above. They are souls of the deceased and souls of the environment. These are their nature.
God of Abraham doesn't have a concrete nature like this. Love, compassion, etc are emotions they aren't concrete terms that define god as an actually existing person. He sounds abstract.
If god exists and he is the only god, what is his nature and how can you define it in concrete terms so it makes sense that only one god can exist in that context instead of more than one?
