Are you serious? Is Sodom still burning? It is clearly referring to the eternal fire.
That is my point, Sodom and Gomorrah are not still burning.
Unless we are going to assume that "half" of the fire God poured down on Sodom and Gomorrah disappeared, and half of it went to some underworld where he took the wicked souls of Sodom and Gomorrah to be tormented?
That's really stretching things beyond what the text says.
It says Sodom and Gomorrah suffered the vengeance of "eternal fire". What was that "eternal fire"? It was the fire that God poured down upon these cities---"fire and brimstone [sulfur]".
These cities are now pure ash, all 5 of them. The WHOLE land around the Dead Sea is filled with sulfur and ash, which is 98% pure--found nowhere else in the world.
That fire is still not burning. It is ash. Even Josephus testifies to this!
Hey, you are free to say God split his fire in two-places, where part of the fire came down and burned up the cities and all the inhabitants, while the other half he took the souls of the burned up wicked into a separate fire place where they are still burning--- but that is not what the text says.
It says:
"Even as Sodom and Gomorrha, and the
cities about them in like manner, giving themselves over to fornication, and going after strange flesh, are set forth for an
example,
suffering the vengeance of eternal fire." (Jude 1:7)
But Peter elsewhere explains
what "eternal fire" does:
"And turning the cities of Sodom and Gomorrha
into ashes condemned them with an overthrow, making them an
ensample unto those that after should live ungodly" (2 Peter 2:6)
Let the texts speak to you, and do not read more into it than what they say. The same "eternal fire" is what turned "Sodom and Gomorrah" into "ashes". That's what "eternal fire" does. It is a fire that comes from God. God is a perpetual "consuming fire".
Nothing unholy can live or survive in it.
