What I mean by context is worldview - having the ancient Israelite or first-century Jew in your head as you read. How would an ancient Israelite or first-century Jew read the Bible - what would they be thinking in terms of its meaning? The truth is that if we put one of those people into a small group Bible study and asked them what they thought about a given passage meant, their answer would be quite a bit different in many cases than anything the average Christian would think. They belonged to the world that produced the Bible, which is the context the Bible needs to be understood by.

God doesn't save us to perpetuate a particular Christian sub-culture. He saves us to advance a supernatural kingdom that is not of this world.

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.

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

Angels can fail because God allows them to make decisions and they are lesser beings than the perfect God. They can go astray, but the task is legitimate. God never tells they aren't allowed to instruct people - "just shut up and babysit them".

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.

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.
