The Torah commands every Jew to write a Sefer Torah: “Now, therefore, write this song for yourselves, and teach it to the Children of Israel” (Devarim 31:19). The Sages derive from this that each person has an obligation to write a Sefer Torah. But why is personally writing one so important?
Imagine someone who builds a business from the ground up. He invests his time, money, and energy into making it successful. When someone criticizes it, he is quick to defend it. Why? Because it is his. An employee may work hard, but the founder has a deeper personal connection.
Perhaps the mitzvah of writing a Sefer Torah teaches us to develop that same sense of ownership toward Torah. Judaism should never feel like something merely inherited from previous generations. We are meant to take personal responsibility for it—to invest our time, energy, and heart into living by its values.
Torah is not simply something we inherit. It is something we must make our own.
