In order for us to receive the merit of our fathers, we need to connect with the Torah and the values of our forefathers, of the generations that preceded us.
The fundamentals of building the next generation of the Jewish people is by connecting them to the attributes of the Tzadikim of previous generations.
Rav Eliyahu Dessler in his work, Michtav Me’Eliyahu, learns from this concept that giving by passing down the Torah of the previous generations to today’s students, is the genuine way of bringing more Emunah to the world.
