I do not know God’s plan. All I can do is try to find meaning in what has happened. And to use this borrowed time to make my life matter more.

I used to sing a song to my children, a song that my father sang to me when I was a child. “Hashem is here,” I would sing, using a Hebrew name for God, pointing with my right index finger to the sky. “Hashem is there,” I would sing, pointing to my right and left. “Hashem is truly everywhere.” That finger I would use to point out God’s omnipresence was taken from me.

I pray that my missing finger serves as a constant reminder to me. A reminder that every single human being is created in the image of God; a reminder that I am part of a people that has survived the worst destruction and will always endure; a reminder that my ancestors gave their lives so that I can live in freedom in America; and a reminder, most of all, to never, ever, not ever be afraid to be Jewish.

From here on in I am going to be more brazen. I am going to be even more proud about walking down the street wearing my tzitzit and kippah, acknowledging God’s presence. And I’m going to use my voice until I am hoarse to urge my fellow Jews to do Jewish. To light candles before Shabbat. To put up mezuzas on their doorposts. To do acts of kindness. And to show up in synagogue — especially this coming Shabbat.

I am a proud emissary of Chabad-Lubavitch, a movement of Hasidic Judaism. Our leader, the great Rabbi Menachem Mendel Schneerson, famously taught that a little light expels a lot of darkness. That is why Chabad rabbis travel all over the world to set up Jewish communities: I have colleagues in Kathmandu, in Ghana, as well as in Paris and Sydney. We believe that helping any human being tap into their divine spark is a step toward fixing this broken world and bringing closer the redemption of humanity. It is why 33 years ago my wife and I came to this corner of California to build a house of light.

Because we are obviously Jewish, identifiable by our black hats and beards, it has also meant that some of us have been targets before. Eleven years ago, my colleagues Rabbi Gavriel and Rivka Holtzberg, who ran the Chabad of Mumbai, India, were murdered with four of their guests. They were targeted by the terrorist group Lashkar-e-Taiba because they were Jewish. And over the years people I know have been harassed and assaulted by thugs in the neighborhood where I grew up, Crown Heights, Brooklyn, in incidents that typically go unreported by the press.

In his vile manifesto, the terrorist who shot up my synagogue called my people, the Jewish people, a “squalid and parasitic race.” No. We are a people divinely commanded to bring God’s light into the world.
