For several decades now, the call to outreach of the Seventh Lubavitcher Rebbe, Rabbi Menachem Mendel Schneerson, of righteous memory, has not only been heeded by his beloved Chassidim; they rear their children with reverence for this calling. If the "central office" in Brooklyn does not have the funds to promote a start-up, the young Chabad couple – as has been documented in Sue Fishkoff's 'The Rebbe's Army' – will go to an uncharted city, find a phone book and start calling names that sound Jewish. No one is more successful in Jewish outreach – no one! – than Chabad. Each and every member of this prestigious Chassidic dynasty sees themselves as put on this earth to help Jews reconnect to their Judaism. People joke that when Neil Armstrong placed Old Glory on the soil of the moon, Chabad beat him to it. Nothing will stop Chabad, and the impact that they have had is one of the greatest successes in Jewish history. When Moshiach comes, I truly believe that this selfless movement of loving Jews will be credited. We all need to learn from them.

Nothing will stop Chabad, and the impact that they have had is one of the greatest successes in Jewish historyI just saw a press conference by Rabbi Yehudah Krinsky of Chabad. Visibly broken and shaken, he offered his condolences to the family of the Holtzbergs, spoke of Chabad's continued resolve to never cease their holy work, and looked into the camera and spoke to the hundreds of Chabad emissaries, assuring them that their work will continue. Knowing that he had the world media focused on him, he encouraged young women to 'add light to this darkness' and light Shabbat candles this Shabbat.

Somehow I think that couples have already submitted their names to '770' (Eastern Parkway – the world headquarters of Chabad) to continue the holy work of the Holtzbergs. I wouldn't be surprised if there was a waiting list. That is the passion, love, dedication and vital nature of the Chabad shliach (emissary). May G‑d strengthen all of them, for all of our sakes.

Today we live in a virtual "Torah community." This past week I met a shliach from a small community in Ontario. He told me that his son goes to school online. Chabad developed an online Torah school for the children of emissaries – so they can always live in a Torah community. But they do more than live in a Torah community—they create such communities.

Our collective hearts are broken over this tragedy. The Holtzbergs lived the life of our Patriarch Isaac, who was bound on an altar by his father Abraham. They lived a life of sacrifice, and unfortunately, died that way as well. But they were able to take the values of the Land of our Forefathers, the Holy Land, their nation of origin, and bring them to Mumbai, a city devoid of Torah-Jewish life.

Their orphaned son will learn of the heroic life and death of his parents, and he will be proud. I would not be surprised if he marries and devotes his life to the Jewish people. With G‑d's help, little Moshe Tzvi – who turned two on Shabbat – will represent his parents in this world as we all greet Moshiach together. I have no doubt that his parents have already been ushered in to meet Isaac, and the other patriarchs, matriarchs and holy leaders of the generations.
