Chelek 17, Ethics of our fathers with Rabbi Eliezer Wolf

Rebbi Chananya says that G-d wanted to bring merit to the Jewish people and therefore gave them an abundance of Torah and Mitzvos.

What is accomplished through the study of the Torah and the fulfillment of Mitzvos? How that changes a person, how that changes the nature of the object used for the Mitzvah, and how learning Torah and doing Mitzvos accomplishes the greatest level of G-d revelation. The Unity of Torah, the surrendering to G-d in Mitzvos, and the refinement of human characters.
