Satan was originally Lucifer or the morning star. Morning is symbolic of the conscious mind and night is the unconscious mind. The morning star is Venus. This star in consciousness, is based on Venus or desire, but in a general sense; motivation and dream. The America dream is a desire; morning star. This drive was good for civilization and advancement. Lucifer evolves over time and becomes Satan, who then further evolves over time and becomes the Devil. It is the same principle of consciousness, but as it advances with time; desire to law to lawless compulsion.
In Revelations, Satan is thrown from Heaven. In the Old Testament Satan was a welcome part of heaven. Satan was God's left hand man in the Old Testament. Satan was in paradise. He was placed in charge of the earth and humans after the fall from Paradise, similar to how a CEO leads a company, but reports to a board of directors; God and Heaven. The lament above is the CEO did not do his job well, leading to him being dispatched from Heaven; your fired! Jude anticipated the change in the Satan principle.
The problem for humanity, after the fall from Heaven; Revelations, was although Satan was thrown from Heaven and loses his role as Old Testament CEO of the earth, nobody on the board of directors told the employees; humans. Although this was announced by Jesus.
Satan, after being cast from Heaven, is sort of like a CEO, who is finishing his contract, but it will not get renewed. But since he is still there, making the calls like before, the employee continue to follow his lead, like the days of old, even though this is no linger fully sanctioned by God. Jesus tries to explain, but the old ways continue to persist. This is no longer the Old Testaments Satan, where God had oversight. Now Satan has gone renegade, but most humans cannot yet see.
The deposed CEO Satan is angry; great wrath and out to sabotage. Much of Revelations is about the Sabotage created by the deposed CEO Satan. This change evolves Satan, into the Devil and Hades becomes Hell. Devil is part of the New Testament. Satan is no longer attached to God and Heaven. The New CEO from heaven is now Jesus.
The historical problem is there is not much in the way of prophesy after Revelations. The employees of the company called earth, are not fully made aware of the change in CEO accept at the beginning. The old way continues, fire and brimstone, such as war and dominance, which is no longer sanctioned by Heaven. Satan deceives the world, while God sits back and waits for the humans to figure it out for themselves. The human get personal revelations from the Holy Spirit. But Satan beats this back over and over. The evil rule and the good are at a disadvantage waiting for the new CEO to appear among them.
