What is striking is how his unremarkable nephew, Lot, somehow manages to achieve what he could not. In fact, Lot single handedly saves an entire town!
As the angels urge him to flee to the mountains, Lot is reluctant and asks if one of the five cities could be spared so that he could find refuge within it. Astonishingly, God agrees! Although Lot does pick the "smallest" town, how was his argument more persuasive than his legendary uncle's?
There was a fundamental distinction between the tactics of the two. Avraham offered words of prayer while Lot was ready to take action. Lot was willing to embed himself into the town with the hope of changing the ethos.
Ultimately he recognizes the hopelessness of the situation and flees. Yet, his determination and idealism won the respect of God. In the end, Lot teaches us a fundamental lesson in life - no matter the odds, action speaks louder than words.
