"For [A FIRE IS KINDLED IN MINE ANGER, AND SHALL BURN UNTO THE LOWEST HELL], and shall consume the earth with her increase, and set on fire the foundations of the mountains. I will heap mischiefs upon them; I will spend mine arrows upon them. They shall be burnt with hunger, and devoured with burning heat, and with bitter destruction: I will also send the teeth of beasts upon them, with the poison of serpents of the dust. The sword without, and terror within, shall destroy both the young man and the virgin, the suckling also with the man of gray hairs." (Deuteronomy 32:22-25)
"Blessed and holy is he that hath part in the first resurrection: on such the second death hath no power, but they shall be priests of God and of Christ, and shall [REIGN WITH HIM A THOUSAND YEARS]. And when the thousand years are expired, Satan shall be loosed out of his prison, And shall go out to deceive the nations which are in the [four quarters of the earth] (i.e., "the four points of a compass"), [Gog] (i.e., "Prince gog, a supernatural entity possessed by the Devil himself"; cf. Rev. 16:13-14), and [Magog] (i.e., "an army of demon possessed rebels amassed from nations at the consummation of the Earthly 1,000 year reign of Christ"), to gather them together to battle: the number of whom is as the sand of the sea. And they went up on the [breadth of the earth] (i.e., "the plains of the land [of Israel]"), and compassed the camp of the saints about, and the beloved city: and fire came down from God out of heaven, and devoured them. 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 AND EVER]." (Revelation 20:6-10)
Even after the Lord's 1,000 year reign upon the Earth, there will be MANY who stubbornly refuse to subject themselves to the Sovereign, Righteous, and Holy Rule of God and His Christ; this demonstrates that their decisions are irremediable due to the hardness of their hearts (cf. Jn. 3:18; Rom. 1:28; 2 Tim. 3:8; Tit. 1:16). The Glorious Presence of God and Christ in His fullest Manifestations, and the Sovereign Power of His Might, was not enough for these rebellious men and women to bow their knees in adoration and reverence of all the Goodness their Creator has displayed. Those who end up in the Eternal Lake of Fire took delight in their sins over living Eternally with the Most Holy and Just God; for this cause, God will give them over to their reprobate hearts what they desire: to commit iniquity without any restraint, and to do nothing [but evil] with each passing moment of their Christless existence (e.g., "hatred, misery, agony, without restraint of evil, malice, brutality, etc.").
"And I saw heaven opened, and behold a white horse; and he that sat upon him was called [FAITHFUL AND TRUE], and [IN RIGHTEOUSNESS HE DOTH JUDGE AND MAKE WAR]. His eyes were as a flame of fire, and on his head were many crowns; and he had a name written, that no man knew, but he himself. And he was clothed with a vesture dipped in blood: and his name is called The Word of God. And [the armies which were in heaven followed him] upon white horses, clothed in fine linen, white and clean. And out of his mouth goeth a sharp sword, that with it he should smite the nations: and he shall rule them with a rod of iron: and he treadeth the winepress of the fierceness and [WRATH OF ALMIGHTY GOD]. And he hath on his vesture and on his thigh a name written, [KING OF KINGS, AND LORD OF LORDS]." (Revelation 19:11-15)
There will be a final effort made by Satan to usurp the Eternal Throne of the Most Sovereign God and Despot: this prophecy depicts the pathetic attempt made by the Devil, who gathers an army which numbers in the millions, if not into the billions. Does God need an army? Christ is accompanied by saints of the Old Testament, the saints of the New Testament, and His angels; this however, does not suggest that His [army] even lifts a finger (cf. Dan. 12:1-2; Matt. 25:31; Jude 14). There will be a bloodbath as the LORD will call upon the birds of the air to tear the flesh off of those waging war against Him, and the beast and the false prophet will be captured and thrown alive into the Eternal Lake of Fire to be tormented forever. It is Christ alone who will take Vengeance on all who have afflicted God and His people (Ps. 149:5-9; 1 Cor. 6:2; 2 Tim. 2:12; Rev. 20:4,9).
"Let the saints be joyful in glory: let them sing aloud upon their beds. Let the high praises of God be in their mouth, and a two-edged sword in their hand; To execute vengeance upon the heathen, and punishments upon the people; To bind their kings with chains, and their nobles with fetters of iron; To execute upon them the judgment written: [THIS HONOUR HAVE ALL HIS SAINTS, PRAISE YE THE LORD]." (Psalm 149:5-9)
