Notably, Zarahemla was destroyed by fire just prior to the appearance of the Savior, 'And there were exceedingly sharp lightnings, such as never had been known in all the land. And the city of Zarahemla did take fire' (3 Nephi 8:7-8; 9:3).

"I do not know what degree of repentance would be required of us to avert some of the things that might be imminent or at least remote possibilities. You recall Abraham's bargaining concerning the destruction of Sodom, how he pleaded that the city would be spared if there were fifty righteous souls, then forty-five, and so on down to ten. I doubt that we shall realize terms as favorable as Abraham was able to secure for Sodom. Apparently he was an astute bargainer, but the ten weren't found, and Sodom wasn't saved. I don't know that ten of a city would be enough to save us today, but I am sure that the degree of our repentance will be taken into consideration. And I earnestly hope and pray that we may give full repentance, and others with us, to the end that our Father in heaven in his mercy and in his patience and in his love for his children, which he has declared, and in whose immortality and eternal life he has stated his earnest interest, will revise his timetables, whatever they may be, according to the degree of our repentance. If he would agree to save a city for ten repentant souls, think what he would do for a whole nation or people who repented!" (Conference Report, Apr. 1950, p. 104)
