NOTE:  Jesus Christ took upon him the form of a servant, was manifested in the flesh, unlike angels because angels are only spirit (Psalms 104:4), to taste death (Hebrews 2:7 & 9) for every man.  Jesus Christ condemned sin in the flesh by dying on the cross for our sins.  Since satan is not reconciled nor are his angels,  "all" does not mean all, but "all" pertains to the Body of Christ---His sheep.

1.  GOD WAS MANIFESTED IN THE FLESH MADE IN THE LIKENESS OF SINFUL FLESH:

Romans 1:3 Concerning his Son Jesus Christ our Lord, which was made of the seed of David according to the flesh;
Genesis 3:15 And I will put enmity between thee and the woman, and between thy seed and her seed; it shall bruise thy head, and thou shalt bruise his heel.
Hebrews 2:14 Forasmuch then as the children are partakers of flesh and blood, he also himself likewise took part of the same; that through death he might destroy him that had the power of death, that is, the devil;
Hebrews 2:16 For verily he took not on [him the nature of] angels; but he took on [him] the seed of Abraham.
Psalms 104:4 "...Who maketh his angels spirits;..."
Romans 8:3 "...God sending his own Son in the likeness of sinful flesh, and for sin, condemned sin in the flesh:..."
Philippians 2:7 "...took upon him the form of a servant, and was made in the likeness of men:..."
Hebrews 2:7 Thou madest him a little lower than the angels; thou crownedst him with glory and honour, and didst set him over the works of thy hands:
Hebrews 2:9 But we see Jesus, who was made a little lower than the angels for the suffering of death, crowned with glory and honour; that he by the grace of God should taste death for every man.
Hebrews 2:17 Wherefore in all things it behoved him to be made like unto [his] brethren, that he might be a merciful and faithful high priest in things [pertaining] to God, to make reconciliation for the sins of the people.
Hebrews 7:16 Who is made, not after the law of a carnal commandment, but after the power of an endless(akatalutos) life.
Hebrews 7:24 But this [man], because he continueth ever(aion), hath an unchangeable priesthood.
Romans 1:20 For the invisible things of him from the creation of the world are clearly seen, being understood by the things that are made, [even] his eternal power and Godhead; so that they are without excuse:
Hebrews 12:23 To the general assembly and church of the firstborn, which are written in heaven, and to God the Judge of all, and to the spirits of just men made perfect,
1Peter 4:17 For the time [is come] that judgment must begin at the house of God: and if [it] first [begin] at us, what shall the end [be] of them that obey not the gospel of God?
 
 

2.   SATAN IS CONDEMNED AND ALSO THE FALSE PROPHET ARE TORMENTED FOREVER:

Revelation 20:10 And the devil that deceived them was cast into the lake of fire and brimstone, where the beast and the false prophet [are], and shall be tormented day and night for ever(aion) and ever(aion).

Revelation 12:9 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.

(note:  1Corinthians 15:26 "..The last enemy...destroyed [is] death..." has now been fulfilled in this verse which is revealed in Revelation 21:1 "...no more sea...", Revelation 21:4 "...no more death...", Isaiah 65:17-20 "For, behold, I create new heavens and a new earth: and the former shall not be remembered, nor come into mind.  (18)But be ye glad and rejoice for ever [in that] which I create: for, behold, I create Jerusalem a rejoicing, and her people a joy.  (19)And I will rejoice in Jerusalem, and joy in my people: and the voice of weeping shall be no more heard in her, nor the voice of crying.  (20)There shall be no more thence an infant of days, nor an old man that hath not filled his days: for the child shall die an hundred years old; but the sinner [being] an hundred years old shall be accursed.  And also in  Isaiah 25:8 "He will swallow up death in victory; and the Lord GOD will wipe away tears from off all faces; and therebuke of his people shall he take away from off all the earth: for the LORD hath spoken [it].")

By virtue of the scriptural proof that satan and his angels are not reconciled back to God, this alone proves the "endlessness" of "aion and aion" of Revelation 20:10.

3.  JESUS CHRIST WILL JUDGE SATAN UNTO DAMNATION

Isaiah 54:16 Behold, I have created the smith that bloweth the coals in the fire, and that bringeth forth an instrument for his work; and I have created the waster to destroy.

John 1:3 All things were made by him; and without him was not any thing made that was made.

Colossians 1:16 For by him were all things created, that are in heaven, and that are in earth, visible and invisible, whether [they be] thrones, or dominions, or principalities, or powers: all things were created by him, and for him:

Matthew 25:41 Then shall he say also unto them on the left hand, Depart from me, ye cursed, into everlasting fire, prepared for the devil and his angels:

Acts 13:10 And said, O full of all subtilty and all mischief, thou child of the devil, thou enemy of all righteousness, wilt thou not cease to pervert the right ways of the Lord?

1John 3:8 He that committeth sin is of the devil; for the devil sinneth from the beginning. For this purpose the Son of God was manifested, that he might destroy the works of the devil.

John 5:22 For the Father judgeth no man, but hath committed all judgment unto the Son:
