Revelation 12:7-9 "Now war arose in heaven, Michael and his angels fighting against the dragon. And the dragon and his angels fought back, but he was defeated, and there was no longer any place for them in heaven. And the great dragon was thrown down, that ancient serpent, who is called the devil and Satan, the deceiver of the whole world—he was thrown down to the earth, and his angels were thrown down with him."
Jude 1:6 "And the angels which kept not their first estate, but left their own habitation, he hath reserved in everlasting chains under darkness unto the judgment of the great day."
The angels “did not keep their proper domain,” Jude says. The phrase “proper domain” in the Greek is ἀρχὴν, meaning “rule” or “beginning.” The fallen angels “did not keep their beginning,” meaning that they did not keep the path in which they were created. In the beginning, the angels were created to be in Heaven with God, praising Him, and doing His bidding. They were made to glorify Him, as were humans, but humans were made to dwell on the earth — not angels. And yet, these angels “left their beginning,” or left their starting position (in heaven). They used the free will God gave them and made a decision to abandon God’s purpose for them.
Scripture says that these angels are fallen angels because they left Heaven. Where are these angels now? In Hell, according to Scripture:
2 Peter 2:4 "For if God did not spare the angels who sinned, but cast them down to hell and delivered them into chains of darkness, to be reserved for judgment;"
If fallen angels were once in Heaven, but are now expelled from Heaven, then there was a change in their place or abode that explains why they are called “fallen” angels. These fallen angels are now in Hell, awaiting their eternal judgment that will consign them to Hell for all eternity. Of course, the leader of the fallen angels, Satan himself, gets to appear before the angels as they meet in Heaven despite the fall from Heaven. We find this tidbit of detail out in the Book of Job:
Job 1:6 "Now there was a day when the sons of God came to present themselves before the Lord, and Satan also came among them."
Job 2:1 "Again there was a day when th
