I’ll try to answer your questions. Really, the answers are all connected together, and the best help to understand is to go to the links I frequently provide.
Rev 20:1,2 - Then I saw an angel coming down from heaven, having the key to the bottomless pit and a great chain in his hand. 2 He laid hold of the dragon, that serpent of old, who is the Devil and Satan, and bound him for a thousand years; and he cast him into the bottomless pit, and shut him up, and set a seal on him, so that he should deceive the nations no more till the thousand years were finished. But after these things he must be released for a little while.
When Satan was abyssed, it was a restriction of his power to deceive Christ’s faithful anointed, because we know there were those whose hearts were not faithful to truth, and who left Body and disconnected from Christ. (1 John 2:19; Col 2:18,19) But, we have the account in Luke 10:17-20 when Satan was abyssed – not able to “perceive” how to enact a great deceptive plan to gain authority and power over the anointed.
And the seventy-two returned with joy, saying, “Lord, even the demons are subject to us in your name!” 18 So he said to them, “I saw Satan falling like lightning from heaven. 19 Behold, I have given you the authority to tread on snakes and scorpions, and over all the power of the enemy, and nothing will ever harm you. 20 Nevertheless, do not rejoice in this, that the spirits are subject to you, but rejoice that your names are inscribed in heaven.”
This was the beginning of the “thousand year” reign of Jesus Christ. He never said his reign would be one of peace, as the Wt teaches, but division. (Mal 3:18; Matt 10:34; 1 Cor 1:11; Heb 4:12) It is a time period of spiritual war. (2 Cor 10:4,5; James 4:7) His faithful ones fought it with truth, and entered into the “kingdom of the Son He loves”. (Col 1:13,14) The unfaithful were won over by Satan – they became the enemies at the foot of Jesus Christ and the Father. (Ps 110:1-3; 1 Cor 15:24,25)
These faithful ones, never fell spiritually captive to the Wild Beast from the sea in Rev 13:1,2. They did not “worship” it, which is stated in Rev 20:4. (Eph 6:10,11; Rev 13:4) But, in the time of the end, before the Kingdom of God is ushered in, we find the anointed “kings of the earth”, (Rev 1:5) “overcome”/”conquered” by the falsehoods it promotes. (Rev 16:13-16; Rev 13:5-7) They had no “authority” to “trample snakes and scorpions”. (Rev 9:3,4) This time period is when Satan is free from his symbolic chains of “not perceiving” (the meaning of “abyss”). He then knew how to enact his plan to desperately preserve his kingdom and destroy those in Christ. (Rev 12:12,17; Ezek 21:21,22; Rev 13:1,4; 20:7,8; 16:13-16; 1 Tim 4:1; Rev 13:7,10; Col 2:8; Luke 21:24)
So, In Rev 20, we see first of all, that Satan is abyssed. It is followed by the declaration of those heavenly faithful who never “worshiped the beast”. (Rev 20:4) They did not become slaves to men and to their idol/organization. (2 Cor 11:20; Gal 1:10) But then, Satan is let loose. (Rev 20:7) He gives the “key”, the inspiration, to a fallen anointed one and his dark plan to deceive the last group of anointed, is enacted. (2 Cor 11:13-15; Rev 8:10; 9:1) The organization begins developing. (Rev 13:5,11,13,15-17) From there we see that the “camp of the saints and the beloved city” – the last of the anointed on the earth – are gradually and then fully surrounded by “Gog of Magog”, including people from all nations with them. (Rev 20:7-9) The “beloved city” is “New Jerusalem”, the New Covenant promise of life that they are under. (Gal 4:26) Gog of Magog is another description of the two Beasts of Revelation 13 – One, comprised of “Gentiles” (iron); one coming from the earth, “Jews”, those under covenant with Christ. (clay). (Dan 2:40-43; 7:23; Rev 9:7-9 ) (Isa 64:8; 2 Cor 4:7; Isa 41:25)
They together, are the feet of Daniel’s vision of the statue, and the last power to come over God’s holy people. Is it not true, that the governing leadership has chosen to rule with, and as “Gentiles”, their army of elder helpers; while rejected the anointed “army” of God? (Mark 10:37-45; 1 John 4:20; 3:15;Matt 24:48-51; Rev 13:15,11)
The Greek word for “thousand” in Rev 20:2 is χίλιοι chílioi meaning:“plural of uncertain affinity; a thousand”
“The adjective χιλιοι (chilioi) means a thousand, but note that in the first century, people didn't maintain as strict an arithmetic standard as we do today. There weren't many instances of the number thousand (one thousand of the same things is quite rare in the real world) and when such a thing occurred, it was rarely necessary to precisely count them. In other words: our adjective χιλιοι (chilioi) rather means "a whole bunch; probably somewhere near ten groups of roughly a hundred each".”
Revelation is symbolic, a book of signs. (Rev 1:1) To denote that a “thousand years” is a literal fixed time period in a symbolic book, goes against the meaning of the Bible’s “thousand”, in general. Even in the Hebrew scriptures, Jewish scholars seem to agree that “thousand” indicate a large approximate number. If Jesus’ thousand year reign lasted almost 2,000 years, this doesn’t contradicted the Bible’s meaning of a “thousand”.
“But, beloved, do not forget this one thing, that with the Lord one day is as a thousand years, and a thousand years as one day.” 2 Pet 3:8
We know that “death will be destroyed” when Armageddon comes to an end. (1 Cor 15:26) How then, could death be resurrected a literal thousand years later? The scriptures say that when Satan is free of his chains, he misleads “a number as the sand of the sea”. Those who do not escape his deceit, are destroyed. (Rev 20:8,9) The Beast of Rev 13:1,2 rises out of the sea. Isa 57:20 tell us what “sea” can refer to.
“But the wicked are like the tossing sea, which cannot rest, whose waves cast up mire and mud”.
So, from the “wicked”, the organization/Beast that “makes war” and surrounds the anointed, is born. (Rev 13:1,2; Rev 20:9)
Also, the “saints” cannot be surrounded a thousand years into the Kingdom, since they will be reigning with Jesus Christ. All who reign with him during the Kingdom had already conquered evil, death, and Satan’s deceptions. (Rev 12:10,11; But again, who surrounds them now? The elder body/man of lawlessness who has trampled down the Temple of God (1 Cor 3:16,17). (Matt 24:15,16; Mark 13:14,21-23; 2 Thess 2:3,4; Rev 11:1,2) They have the authority to rule over them, given to them by spiritual “harlots”/false prophets. (Rev 13:11,15; 17:3-6)
We have only this life, this time period to be judged. To think we must gain our physical youth and perfect mental awareness during a trial period in the Kingdom, is well, deceitful stupidity, and a slap in the face of Jesus Christ. Didn’t Satan use a similar tactic with Eve? Both Adam and Eve had life placed before them, but they chose to reject it. They broke their covenant with God. We have life placed before us in Jesus Christ. If we choose men, not inspired, to judge our spirituality, telling us “you will not die” if we remain under their corrupt influential organization, are we not like Adam and Eve, as we fall for their consistent 100+ year old lies? (Hos 6:4-10)
“Very truly I tell you, whoever hears my word and believes him who sent me has eternal life and will not be judged but has crossed over from death to life. 25 Very truly I tell you, a time is coming and has now come when the dead will hear the voice of the Son of God and those who hear will live. 26 For as the Father has life in himself, so he has granted the Son also to have life in himself. 27 And he has given him authority to judge because he is the Son of Man.” John 5”24-27
Anyone who believes and obey Jesus Christ’s teachings does not need to be tested one more time a thousand years into the Kingdom of God. Even the unrepentant wicked do not need to be tested one more time. We are all judged by what we do in this lifetime.
“Do not be amazed at this, for a time is coming when all who are in their graves will hear his voice 29 and come out—those who have done what is good will rise to live, and those who have done what is evil will rise to be condemned.”
I think we need to keep in mind that the teaching of a thousand years of peace is taught by the Wt. How many times have they deceived and twisted the scriptures over the years? Should we trust any of their teachings? (Matt 7:15-20)
Can we imagine faithful Job, Noah, Elijah, Isaiah, Abraham, Moses, Esther, Deborah, having to face yet another test after all they went through while on earth? How absolutely unfair of God to allow Satan to have another go at them. It would be unfair to promise that these will receive eternal life, only to withdraw that promise by allowing Satan to deceive them again, once tasting the bounty of God’s blessings. They, and so many more faithful held on to the promise of eternal, forever, never interrupted…life. These pillars will not need to be taught by anyone, as GB Splane sarcastically explained when speaking about David’s resurrection. He and his false teacher companions have sold their soul to the devil. (Luke 4:5-7).
The ancient faithful ones…“But now they desire a better, that is, a heavenly country. Therefore God is not ashamed to be called their God, for He has prepared a city for them.” Heb 11:16
God is the God of the “living”, not of the eternal “dead”. Matt 22:32 Any faithful ones in the memorial tombs who have lost their physical life, are “living” to God.
So again, the thousand years of Christ’s reign is the “kingdom of the Son he loves”. This is when the anointed over the centuries are judged according to their love of truth, or their rejection of it and rejection Jesus Christ as their Head. It is a divisive spiritual battle that rages even until the end. (Eph 6:10,11) and a gathering of his priests to reign with him in the Kingdom. (Rev 5:9,10)
I mentioned that Wt. is Satan’s “magnum opus”, his greatest work of deceit against the remaining holy ones. Satan was “let loose” to put the plan in action on how to deceive the elect. (Mark 13:22) The advent of the organization, and particularly the lie of 1914, coincides with Satan’s release from the abyss. This event leads to the Great Tribulation/Armageddon now in progress. (Matt 24:21,9,15) It is not something seen in the world, as the Wt. says and which Satan plays into their proclamation, but it is spiritual. His “short period of time”, his “little while” to do his dirty work covers the life of the organization. (Rev 20:3)
Those who grab hold of the skirt of the (spiritual) Jew, come to the banquet, the understanding of Revelation’s scrolls - the “Marriage Feast of the Lamb”…even now. These “little dogs” who are leaving the now “apostate city”, (the organization and its leadership) and are searching for truth are just as important to God as are His priests who serve them, which is the assignment God has given to His “royal priesthood” - to be “ministers” to His children. (Mal 2:7;1 Pet 2:5; Heb 1:14)
Jesus didn’t turn his back on the woman who wanted her child healed. He would not turn his back on any who desire to find wisdom and truth. (Matt 15:27) To this “mountain” of knowledge in the faithful anointed Temple, Isa 2:2 tells us that just after Armageddon, “all the nations shall flow to it”. Isa 60:1-5; 11,14; Rev 21:24-27; Rev 3:9; 15:4; Isa 2:3,4
Again Jesus used stories as illustrations when he spoke to them. He said, 2 “The kingdom of heaven is like a king who planned a wedding for his son. 3 He sent his servants to those who had been invited to the wedding, but they refused to come. (foolish virgins, Matt 25) 4 He sent other servants to tell the people who had been invited, ‘I’ve prepared dinner. My bulls and fattened calves have been butchered. Everything is ready. Come to the wedding!’
5 “But they paid no attention and went away. Some went to work in their own fields, and others went to their businesses. (the duties and attention to “Jehovah’s organization”) 6 The rest grabbed the king’s servants, mistreated them, and then killed them. (disfellowshipping of those anointed who speak truth, Matt 23:34; Rev 13:15)
7 “The king became angry. He sent his soldiers, killed those murderers, and burned their city. (Rev 11:1-7; Jer 23:29)
8 “Then the king said to his servants, ‘The wedding is ready, but those who were invited don’t deserve the honor. 9 Go where the roads leave the city. (leave the organization, Rev 18:4-8) Invite everyone you find to the wedding.’ (Isa 55:1-5;John 13:20; Rev 22:17 The servants went into the streets and brought in all the good people and all the evil people they found. And the wedding hall was filled with guests.
11 “When the king came to see the guests, he saw a person who was not dressed in the wedding clothes ⌞provided for the guests⌟. 12 He said to him, ‘Friend, how did you get in here without proper wedding clothes?’
“The man had nothing to say. 13 Then the king told his servants, ‘Tie his hands and feet, and throw him outside into the darkness. People will cry and be in extreme pain there.’
14 “Therefore, many are invited, but few of those are chosen to stay.” Matt 22
As I mentioned before, total, eternal peace and life, with no looming threat of possible death, will reign in the Kingdom of God because that is what is promised. (Rev chapter 21) It will not be interrupted by an attack of Satan a thousand years into this Kingdom of eternal life. I cringed when I heard the GB member mention the Wt doctrine of a thousand years after Armageddon, during his video on the king of the north. Almost every doctrine offered by the Wt. either began tainted, or became tainted… or is totally opposite from what the scriptures teach from the get go. This is the poisoning of the “waters” by the fallen “star/anointed one. Rev 8:10,11
Why must Satan be released from the abyss?
