The puzzle, though, comes from this citation:
And you, Capernaum, will you be exalted to heaven? You will be brought down to Hades. For if the mighty works done in you had been done in Sodom, it would have remained until this day. But I tell you that it will be more tolerable on the day of judgment for the land of Sodom than for you.” (Matt 11:23-24)
"...if by turning the cities of Sodom and Gomorrah to ashes he condemned them to extinction, making them an example of what is going to happen to the ungodly..." (2 Peter 2:6, see also Jude 7)Sodom, Gomorrah, and the entire valley they inhabited were overthrown because of their sin, but the manner in which they perished demonstrated to all the following generations of what will happen to those who die in their sins outside of faith in Christ.
