THEY reigned with Jesus 1000 years.
It doesn't say Christ reigned only 1000 years.
It's the same as saying that I fly to England and reign with Queen Elizabeth for a year. MY reign was a year, but the Queeen continues to reign. Christ is reigning now, and will for eternity. The issue that many have is Christ's reign is a spiritual Kingdom. Not a physical reign.
The first resurrection was dying in sin, and coming alive in Christ
Example: I know baptism is controversial as well, but think about the symbolism of baptism. It is being buried with Christ. Before you are baptized you are dead in sin. Your sins are washed away and you start your new life as a Christian. I am not saying baptism saves. Water cannot wash sin away, but baptism is a symbol of the burial and ressurection.
Now, when you became a Christian you became a new person. Not physically, but spiritually.
Rom 6:3-5 says, "Know ye not, that so many of us as were baptized into Jesus Christ were baptized into his death? Therefore we are buried with him by baptism into death: that like as Christ was raised up from the dead by the glory of the Father, even so we also should walk in newness of life. For if we have been planted together in the likeness of his death, we shall be also in the likeness of his resurrection."
The 1000 years is the time from Christ's resurrection to his 2nd coming. We as Christians reign with him because we were resurrected from the grave of sin.
Stephen, I will study more on the futurist view.If I find the preterist view is in error then I will admit it, and show why it's error.
