Second Death. “The lake of fire” into which death, Hades, the symbolic “wild beast” and “the false prophet,” Satan, his demons, and the persistent practicers of wickedness on earth are cast is shown to mean “the second death.” (
Re 20:10, 14, 15; 21:8; Mt 25:41) Initially death resulted from and was passed on to mankind as a result of Adam’s transgression; hence “the second death” must be distinct from this inherited death.
It is evident from the cited texts that there is no release possible from “the second death.” The situation of those in “the second death” corresponds to the outcome warned of in such texts as Hebrews 6:4-8; 10:26, 27; and Matthew 12:32. On the other hand, those represented as gaining “the crown of life” and having part in “the first resurrection” are free from any possibility of harm by the second death. (
Re 2:10, 11) These, who are to reign with Christ, receive immortality (deathlessness) and incorruption and hence are beyond the “authority” of the second death.—
