Do you not know that when you give control of yourselves as someone's avadim (slaves) to obey him, you are the avadim (slaves) of the one you obey, whether of Chet (Sin) resulting in mavet (death), or of Lishmo'a b'kol Hashem (Listening to the voice of Hashem, mishma'at, obedience) resulting in Tzedek Olamim?
