Revelation 20
The Thousand Years
1Then I saw an angel coming down from heaven, holding in his hand the key to the bottomless pit
a and a great chain.
2And he seized the dragon, that ancient serpent, who is the devil and Satan, and
bound him for a thousand years,
3and threw him into the pit, and shut it and sealed it over him, so that he might not deceive the nations any longer, until the thousand years were ended.
After that he must be released for a little while.
2 Thessalonians 2
Man of Lawlessness
1Now we request you, brethren, with regard to the coming of our Lord Jesus Christ and our gathering together to Him,
2that you not be quickly shaken from your composure or be disturbed either by a spirit or a message or a letter as if from us, to the effect that the day of the Lord has come.
3Let no one in any way deceive you, for
it will not come unless the apostasy comes first, and the man of lawlessness is revealed, the son of destruction,
4who opposes and exalts himself above every so-called god or object of worship, so that he takes his seat in the temple of God, displaying himself as being God.
5Do you not remember that while I was still with you, I was telling you these things?
6And you know what restrains him now, so that in his time he will be revealed.
paul said he was restrained (bound) 2000 years ago.
