Look what the passage states.
Revelation 20:6 Blessed and holy is he that hath part in the first resurrection: on such the second death hath no power, but they shall be priests of God and of Christ, and shall reign with him a thousand years.
So then, there's a possibility, especially since OSAS is not even remotely Biblical, that one can go from blessed and holy to cursed I guess, and that they don't get to really reign with Christ this 1000 years, even tho this passage says they do? What I'm getting at, if this 1000 years represents now, what happens when they die, but that they have lost this spiriritual resurrection somehow? How then can it be said they lived and reigned with Christ a thousand years? Especially if that reign is supposed to be until He returns?
