Declaration of Faith or Lifestyle Manual?
The most important Jewish declaration, which we are commanded to recite every evening and every morning, appears in our Parsha. The Shema is the declaration of the unity of G-d: Hear O Israel, the L-rd our G-d, the L-ord is one.
The Shema, however, is more than a declaration of faith. Abstract faith is not enough; Judaism teaches that our purpose is to impact life on earth. In the realm of faith, our connection to G-d is theoretical, the Shema reminds us that our relationship with G-d must permeate our daily lifestyle. The Shema then, is not merely a declaration of the unity of G-d, but rather, it is a manual of how to experience the Divine unity in every aspect of our life.
Thus, the Shema continues by describing how the idea of faith effects, not just our understanding, but our emotion as well: You shall love the L-rd your G‑d with all your heart, with all your soul, and with all your might.
The Shema guides us on how to implement the unity of G-d in our thought, speech, and action.
We connect our thoughts to G-d through the study of Torah: And these words which I command you today shall be upon your heart. You shall teach them thoroughly to your children,
We influence our speech through the recitation of the words of the Torah (and the words of the Shema): and you shall speak of them when you sit in your house and when you walk on the road, when you lie down and when you rise.
The oneness of G-d permeates our action through the performance of the commandments, symbolized by the commandments to tie the Tefilin on our head and arm: You shall bind them as a sign upon your hand, and they shall be for a reminder between your eyes.
A personal relationship with G-d has been achieved, yet the Shema is not yet concluded. Because our task is to spread holiness, not only in our own space but rather, to the rest of the world as well. The Mezuzah, the words of the Shema written on parchment which we place on the posts of our doors, reminds us that the light of holiness must spread through the doors of our homes and the gates of our courtyards, and influence the rest of the world as well: And you shall write them upon the doorposts of your house and upon your gates.
