Satan Will Be Bound
Then I saw an angel coming down from heaven, having the key to the bottomless pit and a great chain in his hand. 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.
Listen to the "Verse by Verse" episode covering this scripture.
In Revelation 12:9-12 John described Satan being cast down to the earth “having great wrath, because he knows that he has a short time.” In Revelation 20:1-3 we see the end of that “short time.” Satan’s wrath will have brought a deceived humanity to the brink of destruction, to the point of even fighting against Jesus Christ, our Savior, at His return.
But Christ will easily defeat the combined firepower of humanity, and Satan will be no match for Him either. In order to bring a time of peace and utopia to the earth, the deceiver must be locked up. Satan’s deceptive influences will be blocked for a thousand years, making it much easier for humanity to make the right choices without interference and diabolical temptations.
