Foundations of Faith
Emuna From the Cradle
The main mitzvah upon which all the other mitzvot are structured is emuna, certainty of G-d. The Gemara tells us (Makkot 24) that the Prophet Habakuk "summed up" all the mitzvot into one, saying, "The righteous will live by his faith." Therefore, since we are obligated to teach our children to fulfill the Torah's commandments, it is clear that we must teach them emuna from a very young age – for that is the mitzvah on which everything else stands.
