Toldos - Impact From the Inside

In this shiur, delivered in Ba'er Miriam, Rav Burg explains the difference between the way that Avraham engaged with the world and the way Yitzchak engaged with the world. Avraham was able to have an impact even on the people of Mitzrayim but the effects were not necessarily long lasting. Yitzchak was only able to impact the Pelsihtim but the impact was eternal.
