It appears that the Watchtower teaches that the 1000 year reign starts after Armageddon, which makes sense.
(Revelation 20:6) . . .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 will rule as kings with him for the thousand years. . .
If that is the case, why does the Watchtower preach that Jesus started ruling in 1914, and what backing do they have for his heavenly rulership being more than 1000 years?
