3887 - May your son understand that his Bar Mitzvah marks the start of his commitment to the Torah.

At the first Bar Mitzvah of Yitzchak, when Og mocked the boy and the future of Israel, Hashem said, 'You will see multitudes of thousands and tens of thousands coming from him.' Those who argue that a Torah-centered life weakens Jews are mistaken. On the contrary, a Torah life is a life of eternity, success both spiritually and physically. https://www.torahrecordings.com/rebbe/igroskodesh/012/002/3887
