Jesus preaches the Empire of God that he will bring to the Earth and rule it as its Emperor. What kind of an Emperor would he be? What taste does he give us of his upcoming rule in his teachings, parables and miracles?

Scriptures state that Christ's kingdom that is to come on the Earth has a specific purpose. Christ and his proven followers will reign over the rest of the resurrected mankind for those thousand years and teach them righteousness. But one verse in Revelation (20:5) seems to contradict all the other Scriptures in claiming that the rest of mankind does not wake up during that time. What's the story there?
