As these lines are being written, our brothers and sisters in Israel are facing waves of attacks from the Iranian regime. G‑d's hand is ever present, and we see His protection at every turn. But there are risks.Is there anything we can do? Most of us are hundreds or thousands of miles away, in our own communities. Yet our very being cries out: What can we do?The Lubavitcher Rebbe, Rabbi Menachem M. Schneerson, of righteous memory, taught us that yes, there is something we can do.The Rebbe taught us the power of a mitzvah.A mitzvah, a G‑dly deed, has the power to reach deep into the core of our being—where we are all one, and the physical distance between us is of no consequence. At this core, a positive deed on our part will help bring salvation to a brother and sister in distress.

Rabbi Chaim Nochum Cunin, visiting Israel from Chabad West Coast Headquarters in Los Angeles, wrapped tefillin with a soldier earlier this week while temporarily relieving him of his head gear.

During past conflicts in the Land of Israel, and during times of danger for the Jewish people, the Rebbe made practical suggestions of mitzvahs that would elicit G‑d’s blessings and protection.
