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.
Revelation 12: 7 – 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.
When God created the angels, He made some with temporal life whilst the others had eternal life. Lucifer and the angels he deceived never had eternal life. They were created to be destroyed, and when Lucifer and his angels fell from Heaven, God did not go searching for them, nor did He slay a lamb for them (as He did for Adam and Eve), because they were never a part of God in the beginning.
The other angels, those that did not fall, they were all created with eternal life. These angels are of two classes. The first are those angels which are the sons and daughters of God, whilst the second are those which are the servants of God (Hebrews 1: 13 – 14). All of this reveals to us that those angels which were created with eternal life could not be deceived in Heaven, but the other angels that were created with temporal life, they could be deceived, and when those angels fell, they would deceive those people on the earth who never had eternal life.
As sons and daughters of God, before we came from attribute to flesh, our angel or theophany was already in Heaven standing around the Throne of God (Revelation 5: 11). So when Lucifer went forth in Heaven to deceive the angels, we were already there watching everything that he was doing, and we resisted his lie. We were not deceived in Heaven, but stayed loyal to Michael (Christ), thus when the battle that began in Heaven spread to the earth, we could in no ways be deceived in our fleshly existence, because our angel in Heaven was not deceived, and because by the new birth, we are linked-up with our angel to resist the Devil’s lie and overcome in this evil age.
