If it is unanticipated that rules out Revelation 20:7-11. It also rules out Revelation 19. Neither are those times and events the parousia Jesus was talking about. It is Amil that re-write Scripture to fit their theology. It would also make 2 more parousia for Amil. They would be hypocritics to deny that. They also need to add human opinion that combines two different events and call them parallel, which is forcing a drastic change to both text, when they both are very much expected events, and also separate events.
One event has Satan being loosed after 1,000 years. The other event has Satan in total control of the earth for 42 months, and about to be bound in a pit. Both involving a specific time reference, and an expected conclusion of an expected event. And only one involves Jesus coming from heaven to earth. Revelation 19 is an expected coming. The Second Coming per the OD is unexpected and not involving Satan either.
Much Scripture proves that Jesus is "the first resurrection" (Acts 26:23 and Revelation 20:6), "the firstborn from the dead" (Colossians 1:18), "the firstfruits of them that slept" (1 Corinthians 15:20), "first begotten of the dead" (Revelation 1:5).
Matthew 12:22-29, Mark 3:11, 23-27, Luke 10:18-19, Luke 11:20-22, John 12:31-33 Colossians 2:13-15, Hebrews 2:14-15, I John 3:8, Revelation 9:1-11 and Revelation 20:2 prove Satan was bound, defeated, incapacitated, divested of power, disarmed, brought to naught, undone, stripped and spiritually imprisoned through Christ's sinless life, atoning death and triumphant resurrection. Colossians 2:15 tells us: “having spoiled (or divested or disarmed) principalities and powers, he made a shew of them openly, triumphing over them in it.” Satan has not been rendered immobile or inoperative but is limited in his power, kingship and influence by being defeated on the cross. He is like a dog on a chain. He is shackled.
