What happens to all who do take on the mark of the beast? Only those who do not take his mark during this time will enter into heaven and have their names written in the Book of Life. How does this all end?
Revelation 20:7 When the thousand years are completed, Satan will be released from his prison, 20:8 and will come out to deceive the nations which are in the four corners of the earth, Gog and Magog, to gather them together for the war; the number of them is like the sand of the seashore.
Who are these nations and what about all the redeemed saints ruling with Jesus Christ during His reign? There are only two kinds of people who will initially enter into His millennial kingdom. The first will be the saints. The second will be all true believers who endured through the Tribulation and had not yet physically died.
It is the off-springs of these believers who after a thousand years will once again show how pervasive is the inherited sin nature and how cunning and deceitful is Satan.
20:9 And they came up on the broad plain of the earth and surrounded the camp of the saints and the beloved city, and fire came down from heaven and devoured them. 20:10 And the devil who deceived them was thrown into the lake of fire and brimstone, where the beast and the false prophet are also; and they will be tormented day and night forever and ever.
This last battle will be over quickly as God finally ends the rebellion of Satan and all who follow him. Satan is now eternally condemned and imprisoned. No escape. No more chances. Just eternal, unending punishment. There will be no remorse or repentance.
What about all who took his mark, or who never submitted to Jesus Christ as their own personal King and Lord, and therefore do not have their names written in the Book of Life?
God has revealed this in the next few verses. All for next time.
