Rebbi wept: "One can gain his [portion in the] World to Come in one hour." Why is this reason to weep? Because if one can so quickly earn his Olam Haba, in one moment, so can one forfeit it in one moment. And this is surely reason to moan. We are not only talking about losing one's future world but of losing both worlds. And not only his own personal portion but also that of his whole family; thus he is losing many worlds at one time.
Rabbonim who preside over a community have a special duty to their congregants. It is written about Shimon and Levi, who attacked the people of Shechem, "They came upon the city betach." This applies to the residents of the city, but regarding Shechem and Chamor themselves, it does not say `betach'. This is explained that regarding those two, the brothers had a personal interest in killing them for revenge since they were the principles in the crime, and this act could be condoned. But why didn't the townspeople protest the offense? The `betach' comes to teach us that protest would not have been enough. They should have raised a hue and cry and come out in full force against this crime. Protest would not have been sufficient when action was called for.
Similarly, each and every one of the rabbonim is duty bound, personally and with his whole soul and means, to do whatever he can since this involves souls and the salvation of all Jewry.
HaRav Kanievsky conferred his blessing that whoever does all in his power will be blessed with siyata deShmaya, and in this merit, he and his family will merit bountiful success and all-good.
