Was the destruction of Sodom and Gomorrah the wrath of God or a disciplinary action?
The destruction of Sodom and Gomorrah was a disciplinary action rather than the wrath of God per se. It was an instantaneous wiping out, not the suffering they will experience in the tribulation, and it stands as an example to those who would afterward live ungodly.
Les explains from II Peter chapter 2 that God turned the cities of Sodom and Gomorrah into ashes and condemned them with an overthrow. He says this was not the wrath of God per se, but a disciplinary action, because He did not really make them suffer like they will in the tribulation. It was just an instantaneous wiping out of Sodom and Gomorrah, and it was plowed under. He notes that they have not really proven they have found Sodom and Gomorrah yet; some archeologists are convinced it is under the Dead Sea, but they have not been able to excavate it. It was an instantaneous destruction of those wicked cities, making them an example. The reason God destroyed Sodom and Gomorrah was because of the homosexual lifestyle, and the world is never to forget it. Peter says they are an example unto those that should hereafter live ungodly. Les also mentions that God delivered righteous Lot, who was vexed over the filthy manner of living of the wicked.
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;
