EXOD248 One of the purposes of the Torah, the sole purpose, according to the Talmud Kiddushin 21b, was to teach man how to overcome and defeat his desire for evil. God sets up all of human endeavor as a moral test for the human being. He presents the moral situations, and it is up to us to react properly and defeat the desire to do bad, as God did in providing the manna for the Jews in the desert, which He said was a daily test, as Jews were asked to believe in God's promise for daily manna. If we overcome desire and exercise self-control, then we will get reward, whether it be a slimmer figure when dieting or entrance to the world to come. We can indeed view each act in our lives as a test. Every morning, each adult decides whether to go to work or not. At the breakfast table, we choose to be nice or not nice to our spouse. On the road, we must decide to exceed or not to exceed the speed limit. Children must decide each day whether or not to do homework. Because there are so many small and large moral tests each day, we should not look for "extra" situations in which to test ourselves. The evil desire is difficult enough to overcome as it is. Taanit 20b
