Jews believe in reward and punishment, for example. The Rambam lists this as a fundamental Jewish belief. Yet, with little exception, the Torah does not specify the reward for each mitzvah. This deliberate omission prevents us from using our intellect to try and determine which mitzvos are more important than others, a judgement which may impair our commitment to all the mitzvos equally. The chok plays a similar role.
Every mitzvah has a purpose that adds meaning to our lives.
The rationale of the chok, however, is kept from us, demanding our unquestioned commitment, regardless of whether or not we understand it. The chok is a continuous reminder that the authority of the mitzvah and our obligation to observe it come from the word of G-d. Naaseh, first and foremost, we will accept and observe the Torah. Then venishma, we will commit ourselves to study and understand it. All rights reserved.
