We're on safe ground to presume that self-interest and hubris are at the core of the rebellion.
Michael S. HeiserRebellion against God results in being cast out of his service. God doesn't run the affairs of the spiritual world or our world with rebels on his payroll. They are cast to the Underworld (in the case of the Eden rebel), or a special place in the Underworld (e.g., the offenders of Genesis 6:1-4, who are, to quote Peter and Jude, "kept in chains of gloomy darkness" or "sent to Tartarus"). There are more divine rebels than that in the Bible, but hopefully that scratches the surface enough.
Michael S. HeiserWhy are you uncomfortable with the supernaturalist worldview of the biblical writers? Evangelicals don't want to just say, "Well, the inspired writers were wrong about some of their beliefs about the spiritual world and its inhabitants." That really doesn't work in a confessional situation! So instead we come up with excuses and interpretations that allow us to remake the biblical writers in our own post-Enlightenment image. I understand that impulse, but it's not honest.
Michael S. HeiserAngels 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".
Michael S. HeiserIt's important for people in the Church to realize that the way they talk and think about the Bible isn't the way Bible scholars talk and think about it - and I'm including "Bible-believing" scholars there. There is a wide gap between the work of biblical scholars, whose business it is to read the text of the Bible in its own worldview context, and what you hear in church.
