Jesus thought Sodom and Gomorrah should be remembered when he retold the story:
But the same day that Lot went out of Sodom it rained fire and brimstone from heaven and destroyed them all...Remember Lot's wife. (Luke 17:29,32)
The Apostle Peter's teaching included instruction about Sodom and Gomorrah in his short epistle:
And turning the cities of Sodom and Gomorrha into cinders and ashes condemned them in judgment with a catastrophe, making them an example to them that afterwards would live in an ungodly or wicked manner. - 2 Peter 2:6 (adapted from interlinear Bible)
Abraham prayed and reasoned with God on Sodom's behalf (Genesis 18). Ten righteous men could not be found in the city. Lot and part of his family escaped but the city was destroyed (Genesis 19)
Lot and his daughters lived in a cave for a while afterwards as protection against the destruction of fiery rock and stone again falling from the sky.
