You may be surprised to learn that the name ‘Lucifer’ is used only one time in the Bible. Let’s read Isaiah 14:12-15, “How art thou fallen from heaven, O LUCIFER, son of the morning! how art thou cut down to the ground, which didst weaken the nations! For thou hast said in thine heart, I will ascend into heaven, I will exalt my throne above the stars of God: I will sit also upon the mount of the congregation, in the sides of the north: I will ascend above the heights of the clouds; I will be like the most High. Yet thou shalt be brought down to hell, to the sides of the pit.”

While this portion is written to the king of Babylon, Nebuchadnezzar II, and speaks of the sudden downfall of Babylon, it is also (and more importantly) speaking of the source of the evil in the king of Babylon, Lucifer himself. To answer your question simply, we see that Lucifer was “fallen from heaven.” Notice that Lucifer stated five ‘I wills’:

* I WILL ascend into heaven (in an authoritative sense).

* I WILL exalt my throne about the stars of God.

* I WILL sit also upon the mount of the congregation.

* I WILL ascend above the heights of the clouds.

* I WILL be like the most High.

Yet, in one statement of complete authority, the Lord basically said to Lucifer, “Oh no, you won’t!” He actually said, “Yet thou shalt be brought down to hell, to the sides of the pit.”

Obviously, Lucifer (Satan, devil, dragon, etc.) was of greater strength of even the archangels. We read in Jude 1:9, “Yet Michael the archangel, when contending with the devil he disputed about the body of Moses, durst not bring against him a railing accusation, but said, The Lord rebuke thee.” We find the ultimate downfall of Satan in Revelation 12. Let’s read verses7-9, “And there was war in heaven: Michael and his angels fought against the dragon; and the dragon fought and his angels, And prevailed not; neither was their place found any more in heaven. And the great dragon was cast out, that old serpent, called the Devil, and Satan, which deceiveth the whole world: he was cast out into the earth, and his angels were cast out with him.” This portion is both historic and prophetic. It describes the war that occurred when Lucifer first rebelled, which him being cast out of Heaven. It also describes a future day, during the 7-year Tribulation period, when Satan and his agents are cast down to the earth in defeat. Speaking of that time and Satan being cast out of Heaven, we read in Revelation 12:12, “Therefore rejoice, ye heavens, and ye that dwell in them. Woe to the inhabiters of the earth and of the sea! for the devil is come down unto you, having great wrath, because HE KNOWETH THAT HE HATH BUT A SHORT TIME.”

Some have found it confusing to learn that Lucifer is called the “son of the morning” in Isaiah 14, and Christ is called the “bright and morning star” in Revelation 22:16.
