The Sefer Emunash Shalema quotes the Sefer Mitzvot Zemaniyot , who teaches that it is incumbent upon us to thank Hashem for everything He created for our benefit—and that this form of service is the most powerful of all the mitzvot. The Midrash on Mishlei says that even though Hashem has millions of malachim singing His praises, all He truly desires are the praises of His children. The Kedushat Levi writes that one of the intentions of David HaMelech in composing Tehillim with such magnificent praises of Hashem was his awareness that thanksgiving and praise have the power to nullify all harsh decrees and transform them into mercy and kindness. Recently, I attended a Pidyon HaBen for the eldest of twin boys. During the seudah, the grandfather of the newborns shared the remarkable story that led to this joyous occasion. He explained that his daughter and son-in-law had been childless for nearly six years, with little reason to hope. Doctors could not agree on what the problem was; there were conflicting diagnoses, and they found themselves at a painful standstill. Then, last year, while living in Eretz Yisrael, the couple was taken to a certain rabbi for a berachah . When they arrived, the rabbi advised them to become people who constantly thank Hashem for everything. He acknowledged how hard it was for them to be happy in their situation, yet he told them how wondrous it is to express gratitude even when it feels impossible. He urged them to spend time every single day thanking Hashem for all their blessings—and even to thank Him for not yet having children. He gave them a sefer on the subject of hakarat ha-tov , and said, "In the merit of your thanking Hashem, you should be blessed with children." At first, it was difficult for them to feel genuine appreciation in their circumstances. But they persevered, practicing gratitude each day until their hearts began to change. Soon they truly felt grateful for everything Hashem had given them. A few months later, the woman called her father in America, her voice bursting with excitement. "It's a miracle!" she exclaimed. "Baruch Hashem, we're expecting!" The family rejoiced, celebrating with tears of happiness. But only three days later, tragedy struck—the pregnancy was lost. The joy turned to heartbreak. Yet in the midst of their pain, the husband gently told his wife, "Maybe this is our test—to see if we'll still be thankful after disappointment. Let's rise to the challenge and keep thanking Hashem, even for this." They continued their daily words of thanks with renewed faith. A few months later, another miracle occurred: she was expecting again. This time, it was double joy—they were told it was twins. Nine months later, she gave birth naturally to two healthy boys, and the family celebrated two berit milot and a Pidyon HaBen . (The earlier miscarriage did not affect the pidyon , since it had occurred very early on.) Thanking Hashem is one of the greatest acts we can perform—especially when it's hard to do. Each of us has so much to appreciate. And when we cultivate hakarat ha-tov , we draw down mercy, kindness, and blessing upon ourselves and the entire world.
