"Divine providence arranges our lives in light of true happiness as our end, because God is good and loving. This does not necessarily include happiness in the shallow sense. In fact, to be truely happy, we need to be deprived of much happiness in the shallow sense. For true happiness requires wisdom, and wisdom requires suffering. As Rabbi Abraham Heschel says so simply " The man who has not suffered, what can he possible know, anyway?"
