Does the resurrection from the dead seem like a mystery to you?
Paul brings clarity to this often-overlooked biblical truth while acknowledging human mortality: "For as in Adam all die, even so in Christ all shall be made alive. But each one in his own order. Christ the firstfruits, afterward those who are Christ's at His coming" (1 Corinthians:15:22-23For as in Adam all die, even so in Christ shall all be made alive.But every man in his own order: Christ the firstfruits; afterward they that are Christ's at his coming.).
Paul describes an order of resurrections commencing with "those who are Christ's at His coming," which Revelation:20:5 refers to as "the first resurrection." An order of resurrections commencing with one called "the first" means there are subsequent and sequential resurrections—and indeed these are described more fully elsewhere in the Bible.
