I am starting to understand now thanks to many of those here. I could understand how Jesus could be called a "morning star", but I am not sure as to why Lucifer was also given this title. Is this referring to how great of an angel he was?
"When the morning stars sang together", is this referring to all of the angels?
Good question. I've studied this and it's a hard one to get an answer on because there's a lot of information we don't really have about these non-carbon based "life forms" called "angels".
Seems though that Satan was an "angel of rank". He was up there in the "high command" (what ever that constituted). So when he fell; he went down with full knowledge of the entire battle plan, so to speak. It was an act of treason upon the highest order and the cause of that fall was pride. Scripture speaks a lot about Satan being prideful.
We often think of "pride" as being boastful and arrogant (which it is) but it's also self righteous. Another poster in this CF had once pointed out that Satan was the best "pharisee" of all time. Yeah, he can be "base of all creatures" morally and ethically; yet his greatest deception is false religions and works gospels. That's where he's most successful in taking down multitudes of people.
So Adam was made in the image of God as the highest carbon based life form to rule this planet. Was Lucifer the "angelic version" of Adam? (I don't know?). In the sense that he apparently ranked close to God of all the orders of created non-carbon based entities called "angels"; yes we could say he was similar to Adam.
Now this is hypothesis upon my part, yet based on different things in Scripture; I believe Lucifer was jealous of Adam. (He was certainly jealous of Christ!) And this is my guess as to what motivated Lucifer to "take down" humanity. There's no redemption plan for angels; so unlike fallen humanity, it seems "angels" who fall become "depraved totally" (as opposed to another theological term that describes the fall as having created in humans "total depravity". "Total depravity" relates to a state of spiritual deadness; yet does not mean to be totally without morals, ethics, or the ability to do human good.)
That is not the same thing though as being "depraved totally"; which I think is what happened to Satan. Satan is a "take no prisoners" "no holds barred", "ends justifies the means", "anything goes" kind of entity. No conscience, no moral restrictions. Any means necessary to destroy every thing that he can possibly destroy with maximum "collateral damage". Merciless. Depraved totally!
And because of this state; God totally reigns over Satan's capacity to carry out destruction. Satan is like "the dark side of the force"; or even the Borg in Star Trek. In the ultimate quest for "perfection"; power becomes the dominant objective to exercise that quest. I don't think the ascertaining of power is actually Satan's ultimate goal; because God is so much greater than just His omnipotence. Satan's desire is to supplant God. Which if you think about that; it's actually a pretty stupid endeavor. How can any created thing compare to an entity who's absolutely infinite in the entirety of His capacity? It's laughable. Not that men and other entities don't try; but it's laughable!
So in that sense "morning star" (being the one who rules the day) has a Divine counterpart (Christ) as well as a created reflective counterpart (Lucifer). Lucifer is spoken of as "the god of this world" and he reigns over a kingdom that's superseded by a greater Kingdom ruled by God himself. Christ was able / given authority to reign over both King/kingdoms by becoming a created entity Himself. So when He was incarnated; (to use the language of Star Trek again) it was like the Borg assimilating an intelligence they suddenly realized they could not control. ("Oh no; we're.... (insert word of choice)!)
So for what my hypotheses are worth; there's my ponderings of what I think possibly happened with Lucifer.
