This is certainly something to ponder and think on. I have heard many appologetics comparing the many gods of heathens to our one god in order to say God is just one. But I can see what you are saying here. Even though they might have more than just one god, each of these gods is still made up of just one one. As you said, Baal is just one.
So to compare our God to this, would be saying he is like them. The idea of a full kingdom of beings united in perfect love, as you say, is something marvelous to comprehend. It certainly is not in our world.
It is surely a high ideal to try to obtain. would be wonderful to live in such a world.
