R' Chaim Shmuelevitz Zatzal once walked into Yeshiva, and he put down his head and cried. He had just heard that an Israeli soldier was just killed. If it doesn’t get you depressed, being: מִּשְתַתֵף בְצָרַת רַבִּים (feeling the pain of others) is a big Mitzva. But the best thing that you can do for Klal Yisroel is to daven that there should be a Ruach (spirit) of Teshuva. Moshiach is around the corner, and if you care for Klal Yisroel, you don’t want any Yid to be left behind and miss everything. The more kiruv or davening for those unfortunate non-religious Jews, the better. The other day, 30 soldiers were given Tefilin, and they agreed they would always wear them. Also, 200 pairs of Tzitzis were given to the army. A text went out that everyone should try to keep one Shabbos. All the: כֵלִּים (pots) of Treife restaurants were koshered for the soldiers. Daven hard that this should be only a small start, and soon we’ll have the most massive Teshuva movement since Adam HaRishon! This is what Hashem wants more than anything!
