During the millennium (Revelation 20:4-6, 5:10), unbelievers will be
ruled with a rod of iron by Jesus and the church (Psalms 2:9,
Revelation 19:15, 2:26-29) in the sense that unbelievers won't be
able to do just as they please; they'll be forced to worship and obey
Jesus, on pain of great punishment (Zechariah 14:16-19, Psalms
66:3-4).
One of the definitions of slavery is "submission to a dominating
influence" (Webster's). Humans are either submitting slaves
(servants) to the dominating influence of God and righteousness in
their lives, or they are submitting slaves (servants) to the
dominating influence of Satan and sin in their lives (Romans 6:16-23,
Ephesians 2:2, 2 Timothy 2:26, John 8:34).
There's no middle ground. Humans are too weak to stand on their
own; even all together, they're just an infinitesimal speck of dust
before the infinite God (Isaiah 40:15,17), and they're simply no
match against the power of fallen angels and demonic creatures
(e.g. Revelation 9).
So humans today must decide whom they will serve.
One of the other definitions of slavery is "the state of a person who
is a chattel of another" (Webster's). Chattel means property. All
humans are the property of God, for he is the Creator and sustainer-
in-existence of all humans (John 1:3, Colossians 1:16-17, Acts
17:28). He can do with them whatever he pleases (Romans 9:11-24,
Revelation 4:11).
These facts rankle the pride of humans. The word "rankle" is
ultimately derived from the word "draco", which means serpent or
dragon. From the beginning of the current human race, the serpent/
dragon has brought it into rebellion against God by appealing to its
pride. Eve was deceived into disobeying God by her pride: she
wanted to be as a god (Genesis 3:5-6), regardless of what God
wanted at that time.
During the coming tribulation, the serpent/dragon will be cast down
out of heaven to the earth for good (Revelation 12:7-9). He'll know
that his time is short (Revelation 12:12), and so he'll employ all of his
power to bring the entire world into the worship of himself and the
Antichrist (Revelation 13:4-18, 2 Thessalonians 2:9), who will speak
horrible things against God (Daniel 11:36, Revelation 13:5-6).
No doubt these things will include the two facts regarding God and
humans mentioned at the start of this post: God forces humans to
worship him (Romans 14:11), and God owns humans (Psalms 100:3).
The Antichrist and his False Prophet (Revelation 19:20, 13:11-18)
will remove these facts from their proper light, which is that God is
the Infinite Holy Creator, more than worthy of worship by all of his
infinitesimal creatures (Revelation 5:13), who only exist because he
is the one who created them and keeps them in existence
(Colossians 1:17, Acts 17:28).
The Antichrist and his False Prophet could present God and Creation
instead in the false, black light of gnosticism, in which God is a finite,
evil, creator (demiurge) of that which is material, while humans are,
in their true nature, divine spirits who are being wrongly imprisoned
within the material universe; they belong instead in their original
home in heaven, a purely-spiritual realm of bliss (the pleroma).
The Antichrist and his False Prophet could present God's forcing
people to worship him as the act of some deranged tyrant, and could
present God's owning people as invalid as humans owning other
humans in today's society.
But the Antichrist will be a deranged tyrant himself; everyone will
have to worship him and his image on pain of death (Revelation
13:15), and everyone, as if they were his cattle/chattel/slaves, will
have to receive his mark upon themselves (Revelation 13:16-18).
So how will the Antichrist get around this hypocrisy, reviling God as
a deranged tyrant enslaving mankind, while he (the Antichrist) will
be a deranged tyrant enslaving mankind?
Perhaps the way that a Marxist dictator could get around the
hypocrisy of reviling the tyranny of capitalism enslaving workers,
while he's a tyrant enslaving workers. A Marxist dictator could claim
that his dictatorship is necessary in order to completely root out
capitalism, and that once the victory over capitalism is complete, his
dictatorship will end and be replaced by a workers utopia.
The Antichrist could claim that his dictatorship is necessary in order
to root out Biblical Christianity and all other (what he could call)
"enslaving mechanisms of the tyrant god", and that once the victory
over God is complete (Revelation 19:19, 16:14), his dictatorship will
vanish and be replaced by a utopia.
But that will be a lie, a deception of the serpent/dragon who
deceives the whole world (Revelation 12:9). For the serpent/dragon
will know that there will be no victory over God, but only total
defeat (Revelation 19:20-20:3). He will know that his time is short
(Revelation 12:12b). But he will manage nonetheless to bring almost
all of humanity, through its pride, down into the same eternal
suffering that he will endure (Revelation 20:10,15, 14:10-11,
Matthew 25:41,46). He is a king over all the children of pride (Job
41:34).
