good grief dude, The First Resurrection of Rev 20 is The Resurrection of The Just …no zombies …It was people starting to become what 1 Cor 15 Describes. satan was bound from the Heavenly Courts. but people were still free to eat from the tree of knowledge and make their own definitions of good and evil. THE RESURRECTION is in two parts …The Just were the first part …then you have a long period of time of them becoming Adopted …The Thousand Years didn’t start in Chapter 20 …more like 12.
There isn’t a Secondary Resurrection of The Just. The First Resurrection of Rev 20 was 70 A.D. …they could finally be Redeemed.
[Romans 8:23 KJV] And not only they, but ourselves also, which have the firstfruits of the Spirit, even we ourselves groan within ourselves, waiting for the adoption, to wit, the redemption of our body.
Only those in the First Resurrection are Blessed.
[Revelation 20:6 KJV] 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.
