Why the Millennial Kingdom? Why 1000-years of World-peace?

The short version is this: the previous 6000-years of horror, war, famine, murder, perversion, discord, hate, all stand as an example to the faithful angelic creation, those that did not follow Satan in the rebellion, and as an example for the faithful in Jesus who will spend eternity with Him in the New Jerusalem, the consequences of disregarding the divine moral law and the divine will of our Creator concerning Messiah and this previous 6000-years of Hell on Earth will act as a bulwark against future rebellion in the Kingdom where free will exists by necessity in the New Jerusalem. The Millennial Kingdom’s purpose extends far beyond the temporary Realm of Time and humanity and Elohim’s divine, intimate, relationship with His faithful angelic creation is at the eschatological root as Elohim restores holiness and peace to His eternal Kingdom disrupted by Satan’s coup d’état…that coup d’état as the root cause for the Genesis creation narrative.

The 1000-years of prevailing peace upon the Earth; this, while Satan is restrained and made impotent; this, during Messiah’s Millennial Kingdom, will provide a stark, undeniable, comparison/contrast to the previous 6000-years of sinful-suffering Hell on Earth; again, providing proof to the faithful angels and observant humanity that Satan is the demonic root of all horror (John 8:44) and it’s important to note that Jesus entered the temporary Realm of Time specifically “to destroy the works of Satan” (1 John 3:8b) via a battle strategy (Genesis 3:15) revealed as the Gospel first in Genesis 3:21 and through Jesus’ victory over Satan’s works (death-Hell-the grave) at Golgotha via the New Covenant (Matthew 26:28); this divine victory via the Gospel was ordained “before Time began” (2 Timothy 1:8-10).

The 1000-years of pervasive peace during the Millennial Kingdom will provide an undeniable stark comparison/contrast relevant to obedience=peace/disobedience=suffering and to add a final evidentiary proof to all living creatures that Satan is the demonic author of all wickedness, Satan will be released from captivity at the culmination of the Millennial Kingdom and once again Satan will deceive the Nations and inspire mankind to rebel against Elohim (Revelation 20:7-9); this time, Elohim will destroy the aggressors by fire; hence, the “Judgment of the Condemned” that follows the final rebellion (Revelation 20:10-15) where Sheol-Hades/Torments will give up the dead via the “resurrection of the condemned” (John 5:29) and those whose names are not written in the Lamb’s Book of Life will suffer commensurate with their sin committed while in body and ultimately die the “second death” in Hell, the Lake of Fire as the Earth is purified by unconscionable heat (2 Peter 3:10), purified, from which a New Earth and New Heaven will manifest (Revelation 21).

Ultimately, finally, the entirety of the faithful angelic creation will concur with Elohim that their former “boss,” Satan, does indeed deserve suffering-torment forever in the Lake of Fire (Revelation 20:10; Matthew 25:41); hence, Elohim will have destroyed evil and restored holiness to His eternal Kingdom via His own selfless love as demonstrated at Golgotha via Messiah (John 19:30).
