There are three main stories involving Lot. The first is when his shepherds argued with Abraham's, resulting in Lot moving down to the lush, but sinful, city of Sodom. The second is when Abraham rescued Lot and the Sodomites from four mighty kings that had captured them. This was a brilliant military victory where Abraham, with just a few hundred soldiers, defeated four powerful armies.
The most significant story, however, is how Lot was rescued on the eve of Sodom's destruction. When we think of an individual being saved from a cataclysm, we think of Noah. It must be that Lot had a certain virtue that raised him to that same level. What was it?
The Torah tells us that Lot was saved after God remembered Abraham. The Ramban suggests that Lot did not possess sufficient merit to be saved by himself, so the merit of Abraham was needed to save him. Abraham had extended much effort to rescue Lot from those kings. Perhaps God was doing Abraham a favor, so he should not feel that all his effort was in vain.
Rashi, however, quotes the rabbis who explained that Lot had actually done a great deed for Abraham. When Abraham had first arrived in the holy land, a famine drove him, his wife, and his nephew down to Egypt. Abraham feared that the Egyptians would kill him to take his beautiful wife, so he requested that she tell them that Abraham was her brother, not her husband. In this fashion, even if Sara should be taken away, Abraham's life would be spared.
The Rabbi say that Lot knew this plot and allowed it to go forward, not revealing the truth to the Egyptians. It was this merit that saved him from the destruction of Sodom. Some ask, however, why this act was so meritorious? After all, what would Lot gain by telling the Egyptians that Sara was Abraham's wife? An answer is given that, at that time, before the birth of Isaac and Ishmael, Lot was Abraham's heir. Had Abraham been killed, Lot would come into a large inheritance. Nonetheless, he put his own self-interest aside and protected his uncle.
This will be a key an understanding just why Lot was rescued, and why his stories have much to teach us. The most important character trait is here. Let us delve further.
A fourth story involves Lot's daughters and this same trait. After Sodom was destroyed, Lot and his daughters fled to a cave. The daughters were convinced that, once again, humanity had been destroyed and they were the sole hope for the future. The older daughter suggested that they get their father drunk and then become pregnant by him. So it was that they became the progenitors of the nations of Ammon and Moab. The question is, was this a good deed that they did or not?
There seems to be a divide among the rabbis on this question. They are critical of the immodesty of the older daughter, and critical of Lot who may have been aware of what was happening. Others, however, see Divine Providence in their actions, and praise them for their deeds. On what does the argument rest?
The Torah says that the daughters feared that "there is no man to come to us as the way of all the world." Some rabbis interpret this to mean that they believe that the world of been destroyed, just as in the days of Noah. Others, again, are more critical and say that these daughters knew that there were humans elsewhere, but feared that none of them were worthy to be their husbands. They just weren't as good as their father, so...
Let's follow the first assumption, that they really believed the world had been destroyed. And let us contrast that with the experience of Noah and his sons after the flood. After the flood, Noah, perhaps suffering from post traumatic stress disorder, becomes drunk inside his tent. His son, Ham, sees him in his nakedness and does something. What did he do? One opinion is that he raped his father. The other is that he sterilized him. In either case the action he took would not lead to having children.
In the case of Lot, the story is reversed. The daughters get the father drunk specifically in order to have children! What is the difference between the two cases? Perhaps the most important character trait a person can possess: Responsibility. The success of the human experiment depends upon the victory of Responsibility over Selfishness.
Lot was an average person. As a matter of fact, his choice to dwell in Sodom indicates that he was a below average person on the moral scale. But he had one overriding character trait which gave him tremendous merit. His sense of Responsibility showed itself time and again. Responsibility means being concerned about, and ready to act upon, the needs of others, of society, of the world. Lot put his selfishness aside in order to protect his uncle Abraham.
What's more, Lot refused to turn away strangers from his home, even though the welcoming of such guests was considered a terrible crime in Sodomite society. When the mob descended upon his house after he had welcomed two guests, he protected his guests at all costs. He was even willing to put his two daughters at the mob's mercy to do so. (Some question how Lot was ready to do such a terrible thing. Perhaps he learned it, according to his own understanding, from Abraham's willingness to endanger Sara's chastity to preserve his own life at Egypt. Perhaps he understood that rape is the lesser evil, and life must take precedence. Whether he was right or wrong is the subject of a different discussion.)
The same can be said about Lot's daughters. They felt an overriding responsibility to continue the human race, despite how distasteful the method available to them was. They looked at what happened between Ham and Noah and decided to do the opposite. They provided the wine, they ensured that the children would be born.
And, as a result of these unions, who was born? The nation of Moab, the nation that gave us Ruth the convert. Ruth took responsibility for her mother-in-law Naomi, and as a result, the line that gave us King David and will ultimately bring us the Messiah came into being.
Yes, Responsibility is the character trait that will save the world. Selfishness, the trademark of Sodom, is what destroys the world. The Jewish nation has always felt a tremendous responsibility to improve the lot of humanity. We, as individuals, must be proud of that character trait and strengthen it in ourselves for the benefit of all.
