It is written:
“Then another wonder appeared in heaven: There was a giant red dragon there. The dragon had seven heads with a crown on each head. It also had ten horns. 4 Its tail swept a third of the stars out of the sky and threw them down to the earth. It stood in front of the woman who was ready to give birth to the baby. It wanted to eat the woman’s baby as soon as it was born….Then there was a war in heaven. Michael and his angels fought against the dragon. The dragon and its angels fought back, 8 but they were not strong enough. The dragon and its angels lost their place in heaven. 9 It was thrown down out of heaven. (This giant dragon is that old snake, the one called the devil or Satan, who leads the whole world into the wrong way.) The dragon and its angels were thrown to the earth.” (Revelation 12:3-4, 7-9)
The Bible here teaches us that there was a large percentage of angels (approximately 1/3) who rebelled with Satan against God. We also know how these angels were persuaded to rebel against Heaven. Notice that the text tells us that the serpent drew these angels away with its’ tail. Considering the dependence of Revelation on the Old Testament, we quickly see what John is telling us:
Isaiah 9:15- (The head means the elders and important leaders. The tail means the prophets who told lies.)
Through lies and deception, 1/3 of the angels rebelled against God.
What was the lie? One possibility is that Satan was promoting the old teaching known as the Doctrine of Emanations. Ken Johnson tells us:
“One might understand if Lucifer was angry with God, he might convince one third of the angels of heaven to leave heaven to be alone, away from God. But look at the verses given about Lucifer’s fall. He wanted to be worshiped as God and actually tried to take God’s throne. How could any rational being think for one second that he might have power enough to force the only creator God out of H is throne? No rational being would. Nor would Lucifer; unless, he believed his own lie. What was Lucifer’s lie? Lucifer’s lie was this: God is not separate from His creation. When God puts His spirit into a newly create d be ing, H e looses part of Himself. In the Jewish Kabala this concept is called the Doctrine of Emanations. In other words , if God created 100 billion people and put H is spirit into each one of them, at that point the Bible would say God is still 100% God and Man is 0% God. Lucifer, on the other hand , would say at that point God might be , say , 47% God and all humans collectively would equate to 53% God. Lucifer might have actually believed that if there were enough angels they could overcome God and absorb the rest of what God once was. That, in effect, would kill off God. He probably believed this was the way it had been done for generations of gods /angels and universes. The Doctrine of Emanations would become the basis of all future pagan religions on earth, and the primary cause of the earth’s destruction by a world wide flood.” (Ken Johnson, Th.D. Ancient Paganism: The Sorcery Of The Fallen Angels, 19 (Kindle Edition))
We see that Satan is joined by at least 1/3 of the host of Heaven in his war against God and His people.
