The Bible tells us that Lucifer the leader of angels got proud and rebelled against God. Lucifer aspired to be like God in position, power, and glory, but not in character. He desired for himself the homage of angels that was due to the Creator. Instead of seeking to make God supreme in the affections of the angels, he sought for himself first place in those affections.
Then, Lucifer led a great host of angels to join him. As a result of pride, Lucifer fell “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” (Revelation 12:7,8). Lucifer was defeated and was cast out. “How you have fallen from heaven, O morning star, son of the dawn! You have been cast down to the earth, you who once laid low the nations!” (Isaiah 14:12). Jesus said, “I saw Satan fall like lightning from heaven” (Luke 10:18). In this statement Jesus looked forward to the crucifixion, when the power of Satan would be broken. He saw also the time when sin and sinners would be no more.
The apostle John writes of the great number of the angelic host “Then I looked, and I heard the voice of many angels around the throne, the living creatures, and the elders; and the number of them was ten thousand times ten thousand, and thousands of thousands” (Revelation 5:11). There are “innumerable company of angels” (Hebrews 12:22).
And John the Revelator tells us the percentage of the angels that actually fell with Satan, “…an enormous red dragon…His tail swept a third of the stars out of the sky and flung them to the earth…the great dragon was hurled down—that ancient serpent called the devil, or Satan, who leads the whole world astray. He was hurled to the earth, and his angels with him” (Revelation 12:3–9). The stars in Revelation 12 refer to fallen angels and thus we can conclude that one third of the angels joined Lucifer in rebellion and were cast out of heaven with him.
