Revelation 20:13

Who, now, are these dead people who were in the sea and whom the sea will give up? Surely we are not to think that because a person drowns, his soul does not go to hell, or that his body is preserved in the sea, or—what is still more absurd—that the sea keeps the good dead people and hell the bad ones. No one could entertain such a notion. Surely those are right who take the sea in this text to stand for this world of ours. To indicate, accordingly, that the living who Christ is to find on earth are to be judged along with the arisen dead, John termed the former dead, too. Such are the good "dead" to whom the words were addressed: "For you have died, and your life is hidden with Christ in God." The bad "dead" … are addressed in the verse: "Leave the dead to bury their own dead." There is another reason why living people can be called dead, namely, because they carry around bodies destined for death. This was Paul's thought when he wrote, "The body, it is true, is dead by reason of sin, but the spirit is life by reason of justification"35—a text in which he shows that both life and death exist in a person living in his body, death in his body, life in the spirit.… The sea is said to "deliver up" its dead, because they are presented for judgment living, just as they are; whereas death and hell are said to "give back their dead," because they are actually restored to life. And do not imagine that it would perhaps have been sufficient for John to say death or hell. He said both—death alone for the good people who, although they suffered death, did not go to hell; and hell for the evil people who, after death, suffer the pains of hell.
