It’s Never Too Late

My Rosh HaYeshiva, zt”l, would often quote a powerful Gemara in Menachos, sharing it in a way that left a lasting impression. The following is a partial paraphrase based on various commentaries.
Rebbe Yitzchak teaches that at the time when the Beis HaMikdash was destroyed, Hashem found Avraham Avinu standing in the Beis HaMikdash. Hashem asked, “What is My beloved doing in My Temple?” Avraham replied, “I have come on account of my children.” Hashem responded, “Your children have sinned and have been exiled.”
Avraham immediately began to defend Klal Yisrael. “Perhaps they sinned accidentally?” he suggested. Hashem replied that their sins were deliberate. “Perhaps only a minority sinned?” Avraham persisted. Hashem answered that the majority had sinned. Avraham continued, arguing that even if they had transgressed, the merit of the mitzvah of circumcision should protect them from exile. Hashem responded that they had abandoned that mitzvah as well.
