"We also know that the Son(Jesus Christ Crucified) did not come to help/save angels; he came to help the descendants of Abraham(Human beings)" (Hebrews 2:16 NLT) God created human beings in his own image and likeness not angels hence His original intention with mankind is to have an eternal unbroken relationship with mankind but the jealousy of angel(Lucifer) lead him to sabotage God's original intention hence disobedient angels were eternally condemned but God lead His Son to restore mankind to His original intention via His death on the Cross and His resurrection Hence you see Jesus saying in Matthew 25:41 "Then He will say to those at His left hand, depart from me, you cursed, into the eternal fire prepared for the devil and his angels!" This is to say that anybody who refuses to believe and live by the grace of the death and resurrection of Jesus Christ Crucified is cheating himself or herself and being unfair to himself or herself because they chose to accept the eternal judgement of hell-fire destined for the devil and his angels Even while all mankind sinned via Adam's sin and was JUSTLY CONDEMNED BY A HOLY GOD yet at the same time, this same Holy God chose by His mercy and grace to restore and redeem(buy-us-back-to-His-fellowship/ownership/relationship) through the one and eternal sacrifice of His Only Begotten Son; Jesus Christ Crucified on the Cross of Calvary thus "This is the grace of God, that Jesus Christ tested death for every human being" (Hebrews 2:9) "For God has concluded all human being to disobedience (because of the disobedience of Adam) and at the same time, He has decided because of this His just judgement to show all human being mercy(through the atoning sacrifice of Christ Jesus Crucified on the Cross; His Only Begotten Son)" (Romans 11:32) When the Holy Spirit indwells any human being by faith in Jesus death on the Cross and His resurrection, He does 3-convicting functions and teachings or revelations for that human being 1. He convicts us about sin (that every sin is sin but all sins are produced from not believing in Jesus death on the Cross as the only Son of God and the only atoning sacrifice for sin and salvation and reconciliation with the true living God) 2. He convicts us about righteousness (such that righteousness is not based upon our waiting to see HIM physically to tell us what is righteous or not but He indwells within our mortal-bodies and enables us both to will and do His good pleasures by saying NO to sin and every appearance of sin according to Jesus teachings not according to our personal doctrines or denominational doctrines or personal interpretations of the Holy Bible) 3. He convicts us about judgement (that the prince of this world which is Lucifer and all other disobedient angels have been eternally condemned to hell-fire and they do not have the ability to repent and they will never ever repent and they know that their time on earth is short hence they are trying to deceive as many human beings as possible to reject the gospel of Jesus death on the Cross and His resurrection as well as lead those who have believed to return back to disobedience and the flesh and sin and sinful appearances and remain inside such lifestyle till their earthly death or the second coming of Jesus Christ) (John 16:7-11 AMPC) I hope this clarifies us that the disobedient angels (Lucifer and others) cannot be saved by the redemptive death of Jesus Christ Crucified on the Cross of Calvary.
