One of the Ten Nisyonos of Avraham Avinu was giving himself a Bris Milah. Why was that such a big Nisayon for someone with his level of Mesirus Nefesh? Based on the approach of Rav Moshe Feinstein. Hope you enjoy. Have a great Shabbos. This episode is Liluy Nishmas my grandmother Devorah Bas Tzvi Hirsch, whose Yartzeit is 7 Cheshvan.
