Why did some of the angels fall?
The Bible tells us that Lucifer and many angels fell from heaven. Lucifer the leader of angels was created perfect (Ezekiel 28:14,15). But he chose to rebel against God. He 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.
The prophet Isaiah wrote about Lucifer, “For you have said in your heart: ‘I will ascend into heaven, I will exalt my throne above the stars of God; I will also sit on the mount of the congregation on the farthest sides of the north; I will ascend above the heights of the clouds, I will be like the Most High’” (Isaiah 14:13-14).
Then, Lucifer led a great host of angels to join him in the rebellion. “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). A careful examination of the Scripture references to Michael points to the conclusion that he is none other than the Lord and Savior Jesus Christ (Daniel 10:13; Jude 9).
Lucifer was defeated and was cast out of heaven. And when he tempted humans and overcome them, he became the ruler of this world. “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).
But through Christ’s sacrifice, the Savior won the battle over the devil. Jesus said, “I saw Satan fall like lightning from heaven” (Luke 10:18). Jesus looked forward when the power of Satan would be finally broken – the time when sin and sinners would be destroyed.
What is the number of fallen angels?
The apostle John wrote 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 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). From this passage, we can conclude that one third of the angels joined Lucifer in rebellion and were cast out of heaven with him.
