We're on safe ground to presume that self-interest and hubris are at the core of the rebellion.

If you don't have the worldview of the people who produced the Bible - under inspiration no less, - you can't understand what they were trying to communicate in many respects. Biblical people weren't modern people. That's self-evident no matter how much we try to deny it.

Our contexts are foreign. They derive from church tradition that is thousands of years removed from the people who wrote Scripture and the audience to whom those people wrote.

God wants the world to function in an orderly way, not a chaotic way, so teaching humans to do what's right and what will make for the happiest life isn't going to be off limits.

Ruling the way God wants you to rule means fostering the ordered relationships he desires, not because he is a killjoy, but because that order maximizes human happiness and love for God. Part of that is worshipping only the true God and no other.

If I were one of the gods who just wound up supervising humans, I'd want to influence the decision-makers to live according to the morals that Israel would eventually get in the Torah, and to teach those same principles to their people. I'd also want to make sure they worship no other god but the Most High.

The powers of darkness are still part of the spiritual world - they don't become something else when they rebel against God. Disembodied believers are, by definition, also part of the spiritual world. So are God and Christ.
