Ziongate “On top of that, until bar mitzvah the child has a yetzer harah but not yetzer tov. Why?”
Because otherwise there would be no struggle… Which would defeat the purpose of our creation. The point of our being, ever since chet etz hadaas when good and bad were mixed together, is to separate the good from the bad by our everyday choices. Every time we struggle but reject the bad we expect are grappling with, it makes the world a more G-dly place.
Every adult knows that bad choices (often) result in instant gratification and long term suffering. Good choices may require sacrifice in the short term but bring long term happiness and satisfaction. For every mature person then, it should be a no brainer what to choose, which would mean we don’t have a choice as there is only one credible choice.
Why do we struggle then and resultantly elevate the world? Because in our youth, for the first 12-13 years, we were accustomed to living by instant gratification and desiring that which looks good on the surface. When we get introduced to a new deeper perspective as a bar / bas mitzvah, we struggle to turn that way of living around.
But the purpose is the struggle (for most people. Tzaddikim are a different category.) and most people were created for the sole purpose of struggling with the bad and overcoming it on many different levels. This avoda itself gives Hashem much much nachas (see my earlier post regarding Yaakov and esav etc)
