The two different approaches to the Torah: the “perfect Torah” and the “evolving Torah” approaches are related to a broader theological question about the nature of the mitzvot: Do the mitzvot reflect God’s ultimate and unconditional will (kvayachol), or do they reflect God’s instrumental will for humanity, providing an instruction manual for how to redeem the world? In other words, is the main purpose of the mitzvot for the sake of God (i.e. that humankind should fulfill God’s wishes) or for the sake of man (i.e. that God’s plan for humanity should be realized)?
Judaism possesses a profound understanding of the human condition, of our need to hear in the deed. Through the external observance of a mitzvah we may begin to grasp its exalted meaning, to hear its inner voice. Contemplation about the mitzvot without actually fulfilling them makes one deed-deaf. The profound meaning of a mitzvah may only be understood by experiencing it.
