The "eternal" fire that burnt Sodom went out long ago. It ended. It wasn't "eternal". Neither is the so-called eternal punishment (correction) of unbelievers.
Jude CLV
5 Now I am intending to remind you, you who once are aware of all, that the Lord, when saving the people out of the land of Egypt, secondly destroys those who believe not." 6 Besides, messengers who keep not their own sovereignty, but leave their own habitation, He has kept in imperceptible bonds under gloom for the judging of the great day."
7 As Sodom and Gomorrah and the cities about them in like manner to these committing ultra-prostitution, and coming away after other flesh, are lying before us, a specimen, experiencing the justice of fire eonian."
"7 The destruction of Sodom and the surrounding cities is still apparent to all who visit the region. In this way these cities are experiencing the justice of eonian fire. The fire has long ceased but its effects will remain and testify to God's judgment until the close of this eon, after which Sodom shall return to her former estate (Ezek.16:53-56)"
As was shown before, Origen sees "aion-ion/eternal fire"[lit. eon-ian fire] as corrective!
Eon-ian just speaks of duration, whether short or long, according to the subject and context.
"The justice of fire eonian is disciplinary and corrective (cf Jude 7)."
The Lord's destruction of Sodom etc purified the human race alive on earth from wickedness. Thus also will he do with individual sinners hereafter.
