Let's clear up this tiny little matter about Christ's ruling. WTBTS has unwittingly said what the Bible has been saying all along. Christ's rule is not just 1000 years long. The 1000 years is the length of time that the holy ones are to rule with Christ.
Rev 20:4-6: "And I saw thrones, and those who sat on them were given authority to judge. Yes, I saw the souls of those executed for the witness they gave about Jesus and for speaking about God, and those who had not worshipped the wild beast or its image and had not received the mark on their forehead and on their hand. And they came to life and ruled as kings with the Christ for 1,000 years. (The rest of the dead did not come to life until the 1,000 years were ended.) This is the first resurrection. Happy and holy is anyone having part in the first resurrection; over these the second death has no authority, but they will be priests of God and of the Christ, and they will rule as kings with him for the 1,000 years."
It's true that WTBTS views Christ as ruling only for 1,000 years, though. They call it "Christ's Thousand Year Reign" and the "Thousand Year Reign of Christ". These are both incorrect. The Bible speaks of him ruling forever. (Isa 9:7; Luke 1:22,23). Even after the 1,000 years, Christ is shown as the Lamb having a throne in New Jerusalem along with God. (Rev. 22:3,4). 1 Corinthians 15:24-28 speaks of Christ handing over the Kingdom at the end and subjecting himself to his Father. That doesn't mean he stops ruling as a king. To me, it means that he fully accomplished that which his Father appointed him to do, up to and including abolishing death. After that, based on Revelation 22:3, 4 it seems they rule together as co-rulers.
The 1,000 years, though, only applies to the time Satan is abyssed, and is also the length of time that those holy ones are to rule with Christ.
This is how I presently understand things.
