The Book of Devarim seems like a mere repetition of the previous four books, just related by Moses rather than G-d Himself. In truth, when Moses ‘channels’ the words of G-d he makes them intelligible for humanity at a finite physical level. Each one of us, with our unique personalities, needs to take the words of Torah and express them in our own different individual lives. That makes us a co-creators of an unfinished creation.
