Because they are the dead brought back to life [resurrected] in their old bodies for the sole purpose of facing the Great White Throne Judgment.
If it is the second resurrection, how does it come before the second death?
Everyone who takes part in this second resurrection faces the GWT Judgment and dies the second death. They are all cast into the Lake of Fire [v15].
I always thought that there is a physical death and a spiritual death. I assume that there is a physical resurrection and a spiritual resurrection. Typology would seem to suggest this. If you do not die the second death, you will not need the second resurrection. If you die the second death you will not be offered the second resurrection. Thus, if there is a second resurrection, it could apply only to Christ.
I assume that since Christ did not die the physical death in our place, that it is the spiritual death that he was talking about when he said, “he that believeth in me shall never die”
