Avraham vs. S'dom

We have been learning about how אברהם is the paradigm of צדק ומשפט/social justice. We see many examples of אברהם as this perfect example of social justice. The first story, from פרק י''ח, which I found extremely surprising, אברהם is talking to Hashem and he stops just to go up to the 3 men to see if they needed anything. Through this story we see exactly to what extent אברהם goes towards helping people. The second story, also from פרק י''ח, is when אברהם debates with Hashem in order to save סדם - a society that was full of people who didn't act morally and ethically, which was all that אברהם stood for. At first the two stories don't really seem to be connected and that they shouldn't come after one another in the Torah. However when you compare the actions of the two people in each story, it makes it clear as to why the two stories are connected and come after one another.
When we learn about אברהם, we learn about his intense passion for צדק and משפט. He focused on taking care of those who were lower than him, and spreading the ideas of ethical monotheism to the בני ישראל. He wanted to create a society that embraced the שבע מצוות בני נח, acted בצלם אלקים, and established a society based on צדק ומשפט. We see how important these concepts are to אברהם when they are put into action as he tends to the angel's needs. We get an even greater sense of how important they were in comparison to the values, or lack thereof, of סדם .סדם was a society that was the antithesis of everything that אברהם stood for, and even though this was true אברהם still fought for them when Hashem sought to destroy them. This really shows us how true אברהם was to what he believed in, and that he was very understanding and caring towards others. By having the two stories one after another, it helps us make an easy, direct comparison between the two.
