Devarim 5775

The Ramban starts off his introduction to Sefer Devarim with stating how it is called the "Mishna Torah" because Moshe goes through many mitzvos with Bnei Yisroel. These are to warn them to follow Hashem's commandments. And Moshe doesn't just do this once or twice, he constantly warns them because they need to be. This is how both learning and mussar work; a person must always be learning and receiving mussar. A person can't just read through things and think his job is done. He must continue to review what he has learned and continue to keep himself from sinning. When we do so, we show Hashem that we want the Beis Hamikdash rebuilt bimheirah biyomeinu.
