The rebellion at the end of the Millenium shows that as long as people are sinful, any peace is can only be obtained by force, and unregenerate people will always rebel against God. The time has now come for the final settling of accounts!! This will pave the way for the final banishment of all evil.
"And I saw a great white throne, and him that sat on it, from whose face the earth and the heaven fled away; and there was found no place for them. And I saw the dead, small and great, stand before God; and the books were opened: and another book was opened, which is the book of life: and the dead were judged out of those things which were written in the books, according to their works. And the sea gave up the dead which were in it; and death and hell delivered up the dead which were in them: and they were judged every man according to their works." - Revelation 20:11-13
The all important thing that will matter:
"And whosoever was not found written in the book of life was cast into the lake of fire." - Revelation 20:15
This would be everybody except those who were living their natural lives in the millenium, and put their trust in God. The other people of God comprise of:
John Lennon (if you remember the Beatles), in a magazine interview said:
"Christianity will end, it will disappear. I do not have to argue about that. I am certain. Jesus was okay, but his subjects were too simple. Today we are more famous than Him" (1966).
You can be sure he won't be saying that at the Great White Throne Judgment:-
"at the name of Jesus every knee should bow, of things in heaven, and things in earth, and things under the earth; And that every tongue should confess that Jesus Christ is Lord, to the glory of God the Father." - Philippians 2:10,11
What a remarkable day that will be! Think of all the people in the world! Every single thing that was said, thought or done will be accounted for!! The God-deniers, the God-haters, the wolves in sheep's clothing - all will show up and give glory to the Lord Jesus Christ.
"And death and hell were cast into the lake of fire. This is the second death...But the fearful, and unbelieving, and the abominable, and murderers, and whoremongers, and sorcerers, and idolaters, and all liars, shall have their part in the lake which burneth with fire and brimstone: which is the second death....And the smoke of their torment ascendeth up for ever and ever" - Revelation 20:14, 21:8, 14:11
