When Klal Yisrael received the Torah at Har Sinai, we received so much more than a set of laws. We received a whole new existence. V'chayei olam nata b'socheinu...What is this life that Hashem has planted within us? What makes a Jew unique? The answer is emunah.All parents want to instill emunah in their children. But in today's confusing and frightening world, how does one accomplish this? Is it even possible? Yes, it is. In this extensive work, Rabbi Ruven Schmelczer takes us through all the steps to give over emunah to our children and students by way of authentic mesorah, and teach them how to live a life of emunah. Using sources from the Torah, Chazal, and previous and present - day gedolim, he proves that emunah can still be taught in the same way it has been given over for thousands of years, without any new - age strategies or methodologies.Written at the request of Rav Mattisyahu Salomon shlit"a, and endorsed with his enthusiastic approbation, this book provides parents and teachers with more than just basic concepts. It is filled with stories, examples, and practical ideas to help children grasp what the Jewish nation received at Ma'amad Har Sinai and what this means to them, as Jews living in a contemporary world. In addition, Rabbi Schmelczer brings hundreds of fascinating quotes from numerous sefarim in an extensive footnote section, for a complete limud directly from the sources.Beyond logic, yet incredibly simple, the ideas presented in The Heart of Emunah will change the way you give over emunah to your children. It will change you as well.
