Ch. 20:1: The scene here is from heaven to earth as an angel comes down to earth having the key and a great chain with him; the key refers to access; to open access or to grant access to – thus access is granted to this angel to bind Satan.
V. 2-3: These two verses describe the following:
1. The Description of Satan: “Dragon, serpent of old, the Devil, and Satan – Gen. 3:1.”
2. The Place in which Satan is bound: “the bottomless pit or abyss the place of the demon hordes that came upon the earth to torment mankind for 5 months (9:1-12).”
3. The length of the time he is bound: “he is bound for 1000 literal years”.
4. The purpose he is bound: “that he should not deceive the nations any more until the 1000 years were ended.”
5. The promise of his being bound: “until the 1000 years is finished.”
6. The promise he will be again loosed: “he must be released after 1000 years are completed.”
V. 4-6: The thrones that John saw are suggested to referring to the Church Age believers as they are seated on throne and judgment was granted to them. There is another group John saw at this time, all those who had been beheaded for their witness of Jesus during the great Tribulation, because they had not worshiped the beast and they had refused to take the mark of the beast – for this they were beheaded – they suffered martyrdom for their faith in Jesus – these are the tribulation or post tribulation believers.
John mentions this group as living and reigning, this means that they have been given their new bodies and they reign with the Messiah for 1000 years.
V. 5-6: This verse is talking about all those who have died in “Unbelief” during the Great Tribulation and the Millennial Kingdom! Those all are blessed who are raised during the first resurrection because during the second resurrection all the wicked dead are going to be raised and all of them are going to be perished in hell forever.
V. 7-9: Satan will be loosed upon the earth
