Partners in the Good Fight

Chapter two is about "Zehirus," which, according to Luzzatto, refers to the need to be introspective and take control of our lives. But, just as the chapter is about to end, the author makes one final, surprising point.

Even if a person keeps watch over himself, it is obvious that he lacks the strength [to defeat the Yetzer HaRa] without Hashem's help, for the Yetzer HaRa is very powerful...

It is generally assumed that we are able to make choices and follow though on those choices because our positive and negative drives are of basically equal strength. But this is a misconception born of the illusion of our experience. The spiritual reality is altogether different.

The truth is that the Yetzer HaRa is far stronger than the Yetzer Tov and we are powerless against it. Left to our own devices, we would lose every battle and commit any and every sin that came our way. If we have ever emerged victorious against the Yetzer HaRa it is only because we have a secret ally called God. God regularly intervenes and saves us. However, God only gets involved if we put up a fight. 

If a person keeps watch over himself then Hashem will help him and he will be saved from the Yetzer HaRa. But if he fails to keep watch over himself, then Hashem will certainly not protect him, because if he doesn't care, why should anyone care about him?

In short, man cannot defeat the Yetzer HaRa alone, but if he makes an attempt then Hashem will help. 

Strange that things would be designed that way. Why did Hashem make the Yetzer Tov weaker than its opponent? Wouldn't it make more sense to have a balance of powers? That way we could save ourselves and Hashem wouldn't have to help us all the time.

The beginning of answer can be found at the end of chapter one.

... And so we learn that the point of man being in this world is only to fulfill Mitzvos, to serve [Hashem] and to withstand [the divinely orchestrated] challenges [of life]... There should be no intent in any act that man does, big or small, other than getting closer to Him...   

In other words, beating the the Yetzer HaRa brings us closer to Hashem. The basic idea is that man is elevated through the struggle and sanctified by the Mitzvah, but now we have new understanding of how the system works.  

Man gets closer to God when he struggles against his Yetzer HaRa because when man puts up a fight, Hashem is at his side fighting with him. This fosters a deep relationship between God and man for nothing bonds two soldiers like a good battle. And since building a relationship with God is the sole purpose of life on earth (as per chapter one), this set-up turns out to be a central feature in the design of man. 

The Gemora in Yoma (39a-b) brings the point home with an astonishing parable. (The translation of the verse is based on Rashi.)

אם ללצים - הוא יליץ, ולענוים - יתן חן  "If [a person wants to associate] with scorners, then he [alone] is [responsible for] becoming a scorner, but if [he wishes to associate] with the humble, then [God will] make him charming" (Proverbs 3:34). When a person is trying to make himself impure, he is given the opportunity, but when a person is trying to be pure, he is helped. In the Yeshiva of Rabbi Yishmael they taught: The parable here is to a vendor who sells petroleum and persimmon. [If] a customer comes to measure out petroleum, the vendor tells him, "Do it yourself." [But if] a customer comes to measure out persimmon, then the vendor says, "Wait for me to do it with you, for then we will both be scented." 

There you have it. God Himself comes to assist man in his strivings because God also wants to enjoy the sweet aroma of Mitzvah and the sweet victory over evil. In the process, a new relationship is forged. It is this singular relationship that gives meaning to all of creation, but everything depends on the few good men who take a stand against their Yetzer HaRa.
