That puts everyone who enters the Millennial Kingdom into the Christian (the Bride) camp, right??? With spiritual bodies who will reign with Jesus...But reign over whom???
Rev. 20:3, 8, states that "nations" will survive the calamaties of the end time, continuing into the millennial kingdom in their natural bodies. A remnant of them, Zech. 14:16 identifies them the remnant "of all the nations" that are "left," i.e., who survive the end time, Armageddon being singled out, "the ones who came against Jerusalem."
