The first five books of the Bible, (The Pentateuch) are the books of the Law, based on the commandments which were revealed to Moses. The Law actually means, "instruction or teaching".

The Law of God; The Torah, is both the expressed will and revelation of God.

The Law was given to bring us to God, cannot eternally save anyone, and is continually the revelation of God bringing understanding to "life in this world". It helps the people of God understand the nature of our life in the Messiah Yahshua. (Gal 3:24, Rom. 3:20, 8:3)
