The final step focuses on joy. Judaism teaches we are inherently capable of transforming the universe—and the world is intrinsically preordained for it. However it can only be achieved if we serve G-d in perpetual happiness, which seems like mission impossible—can we always be happy? We are told: rejoice in your life’s mission. Find happiness in the notion that by dint of your very Jewishness, regardless of background or affiliation, you bring joy to G-d on high by making this world a better place… Now isn’t that something to be happy about?
