In this shiur, Rabbi Zucker discusses the fire of avodas Hashem that Avraham Avinu instilled within Klal Yisrael, from the fiery furnace of Nimrod to the Akeidah. The importance of chamimus and hislahavus in serving Hashem, the deeper meaning of bris milah, and how the fire of kedushah overcomes the fire of the yetzer hara. Ultimately, it is this very fire that will bring about the rebuilding of the Beis Hamikdash.
