The concept of eternal torment is vividly portrayed through the imagery of the Lake of Fire, a place of final punishment described in Revelation 19:20 and 20:10, 14-15. This burning lake, where the Beast and the False Prophet are cast at Christ's return, is later the destination for the Devil, who is thrown into it after a thousand years to be tormented forever and ever. The flames of this lake will utterly consume mortal beings like the Beast and False Prophet, as the elements themselves will melt with fervent heat, burning up the earth and all its works. Regarding who is tormented, Revelation 20:10 indicates a plural subject with the phrase "they will be tormented." If this includes the Devil and the demons, they too will endure the torture and excruciating pain of the Lake of Fire's fervent heat. Being composed of spirit, their suffering might last for a longer, though still indeterminate, time before they expire. The duration of their torment, described as day and night forever and ever, suggests an unstinting thoroughness in the punishment God will administer, ensuring it is most painful and complete as they rightfully deserve.
