Daily Chizuk #1047

One of the Thirteen Principles of Emunah is that Hashem will reward us for every mitzvah that we do. Unlike a human being of flesh and blood, Hashem is able to reward us not just for the immediate effects of our actions, He takes into account the ripple effects of our deeds which can have so many dimensions and continue on for generations to come. In this world, if a mechanic fixes a car, he gets paid his hourly rate. It does not matter if the car he fixed enabled its owner to save lives or to do good deeds. When it comes to Hashem, however, there is a completely different system.
Hashem will reward us for every last effort we put in to Torah and mitzvot. The main rewards will be paid in the Next World, while some deeds will also bear fruit in this world as well.
