In perek zayin of Hilchos Teshuvah the Rambam writes that since every person is a baal bechirah, he should be mishtadel to do teshuvah and lena'er kapav me'chet, so that he dies a baal teshuvah and merits chayei olam haba. One sentence, and four kashos: what bechirah has to do with it, why "yishtadel" when teshuvah is a chiyuv, why the ikar seems to be lifnei misasav when perek beis says teshuvah gemurah is miyad, and how olam haba can be the reason when perek yud calls avodah al menas lekabel schar a lower madreigah. In this Shabbos Shuva drasha the Rav works through each one.

In this episode:

- Why the Rambam says one must do teshuvah even from deos ra'os, when Hilchos Deos only asks us to keep recalibrating to the derech ha'emtza'is

- What being b'tzelem Elokim means for the world a person builds with his own actions

- Schar mitzvah mitzvah and the Ramban's pshat in al menas lekabel pras

- Ya'azov rasha darko ve'ish aven machshevosav, and the shofar's call of uru yesheinim mi'shnaschem

- Konam einai b'sheinah, mehalech k'omed, and a mussar on davening with chiyus
