The Sfas Emes comments on a statement by Chazal: “Any generation in which the Beis Hamikdash is not rebuilt is on the same low spiritual level as the generation which merited the Churban (destruction of the Beis Hamikdash).” He questions the literal truth of this, noting that many pious individuals have lived since the Churban. He asks whether it is fair to say these generations deserved the destruction or if a single virtuous generation will merit the Ge’ula (Redemption).

The Sfas Emes explains that the Ge’ula will come through a cumulative process where each generation’s spiritual achievements build upon those of the previous ones. Every generation that adds spirituality contributes to rebuilding the Beis Hamikdash. This ongoing process is reflected in daily prayers as “Bonei Yerushalayim” (He who builds Jerusalem in the present tense).

He concludes that the Chazal statement refers to a generation that does not contribute at all to this cumulative process. By not adding their contributions, they delay the reconstruction, effectively likening them to those who caused the destruction. Furthermore, he extends this concept to individuals, stating that each person’s actions can help rebuild the Beis Hamikdash. Every Jew must understand that by taking upon themselves the yoke of heaven (Ol Malchut Shamayim) and adhering to Torah and mitzvot, they are contributing a building block to the Beis Hamikdash.

As we approach Shabbat Chazon, the Shabbat before Tisha B’Av, each of us should strive to improve in Torah and mitzvot. Our rabbis agree that we are very close to the final redemption with the coming of Mashiach. Each of us must contribute to achieving this goal. Let’s seek Hashem’s help by doing what He asks of us. While our efforts (hishtadlut) are important, ultimately, everything is directed by Hashem. We have no one else to rely on.
