“See I have set before you today the life and the good, and the death and the evil.” Devarim 30:15
The word “today” in this context appears to be superfluous. Rabbi Moshe Feinstein zt”l explains that it symbolizes the idea that each day this decision to pursue good or evil must be made anew. Failure to choose wisely yesterday does not mean that today is already a lost cause. Likewise, today’s success is no indicator of tomorrow’s outcome. Each day a person must reconsider the options and make a wise choice all over again.
