Parshat Nitzavim starts by proclaiming that “you are all standing here today” (29:9), and then proceeds to use the words “this day” two more times in the next 3 verses, none of which were actually needed for their corresponding sentences to be complete. What significance is the Torah placing on “this day”?
As Rabbi Abraham Twerski points out, there are two natural roadblocks placed before us as we endeavor to become better people and better Jews, and both of these roadblocks can be overcome by focusing on “this day”: The first natural roadblock is our inclination to look ahead at temptations and hurdles we WILL encounter, and our feelings of frustration and helplessness in overcoming those collective obstacles. The Torah therapeutically empowers us to focus on one day at a time, and leave tomorrow’s worries for another day. The second natural roadblock we face is the guilt of our past, which can sometimes make us feel depressed and unworthy. We have today to repent for those things we shouldn’t have done.
With the past behind us, and a whole new year ahead of us, it’s nice to know that we don’t have to wait to become better people… the time is right now, and “this day” is just right!
