Both amillennialists and postmillennialists contend that the binding of Satan occurred at the first coming of Christ and that Satan is bound right now during this present age. They often view the casting of Satan from heaven in Revelation 12:7-9 as parallel with Luke 10:18-19. They point to Mark 3:27 and Matthew 12:25-29 as the fulfillment of the binding of Satan during the earthly ministry of Christ. For them, Satan’s activity and power are restricted during this present age.
However, this contradicts the way Satan is pictured in the New Testament. Satan is called “the ruler of this world” (John 12:31; 14:30), “the god of this world” (2 Corinthians 4:4), “an angel of light” (2 Corinthians 11:14), “the commander of the powers in the unseen world” (Ephesians 2:2), and he is “like a roaring lion, looking for someone to devour” (1 Peter 5:8). The devil schemes against believers (2 Corinthians 2:11; Ephesians 6:11), hinders us (1 Thessalonians 2:18), accuses us (Revelation 12:10), and blinds the minds of the lost (2 Corinthians 4:4). Satan is anything but bound today. He is aggressively opposing the work of God. As someone once said, “If Satan is bound today, he must have an awfully long chain.” Satan is characterized as the arch-deceiver in the New Testament. Yet, Revelation 20:3 says that when he is bound Satan will “not deceive the nations anymore.” This does not fit the current situation. It demands a later time after the Lord’s coming.
Revelation 20:1-3 is very precise and specific in its description of Satan’s binding. It describes four distinct actions by the angel who binds him. Satan is “laid hold of,” “bound,” “[thrown] into the abyss,” and the abyss is “shut and sealed over him” (NASB). The language is very compelling and clear. Nothing even similar to this happened at the first coming of Christ. But it will happen when Christ returns, after which Christ will reign for a thousand years (Revelation 20:4-6).
They (also) have a serious problem explaining Satan’s release at the end of the one thousand years, which they take to be the present age. Revelation 20:1-7 specifically mentions “a thousand years” six times. when John mentions a time period that is general or nonspecific, he identifies it as such by phrases like “a little longer” (Revelation 6:11) or “little time” (12:12). Revelation 20:3 says that at the end of the one thousand years Satan will be released for “a little while.”
