However, there is an obvious question. Rav Dessler explains that the time in the wilderness was the period during which the Jews received much of the Torah. Perhaps G-d was trying to teach us the lesson that we must learn Torah and perform Mitzvos in spite of any outside conditions. As a Rebbe in the Yeshiva, I must, from time to time, chastise a bachur when he is not performing up to par. But life does not work like that.
Life is always full of disturbances.
We are not living in the Garden of Eden. There are financial problems. There are problems with parents, problems with children. That is what the Torah is teaching us through the travels in the wilderness. Life in the desert was not easy.
