What pulls Parashat Vayera together is moral dilemmas. In this shiur we will identify them, look at how Avraham faced them, and see what we can learn from how Avraham faced them. We find four  apparent moral dilemmas: Avraham and the impending destruction of Sodom, Avraham pretending Sarah is his sister while in Gerar, the expulsion of Yishmael, and Akeidat Yitzhak. The dilemmas become more severe as the parasha continues - or do they?We look at a few approaches to  Avraham's criteria and decision-making as he faces each one.
