Revelation 14:9-11:

And the smoke of their torment ascends forever and ever, and day and night they have no rest, those who worship the wild beast and its image, and whoever receives the mark of its name.”

Finally, when the worshipers of the “wild beast” and its “image” are destroyed as by “fire and sulphur,” the evidence of that total destruction will, like smoke, ascend for all time to come.

The completeness of that destruction might be illustrated by what befell the cities of Sodom and Gomorrah. The disciple Jude wrote: “Sodom and Gomorrah and the cities about them . . . are placed before us as a warning example by undergoing the judicial punishment of everlasting fire.” (Jude 7) The fire that destroyed those cities had stopped burning long before Jude wrote his letter. But the permanent, “everlasting” evidence of that fire’s destructiveness remained, for those cities continued nonexistent.
