In a world that is constructed of the story of Purim, everything looks like it’s based on mere happenstance and there seems to be no G-d involved—this is a world of randomness and meaninglessness. Whatever happens, just happens by nature or luck, and what can be more meaningless and depressing than that! Thus, the Rabbis had to decree all the laws for the happiness of Purim, because happiness is not innate to a story that is seemingly happenstance and devoid of G-d. That is the big difference between Purim, where Hashem is hidden, and Passover or Hanukah, where Hashem revealed Himself and made incredible miracles—the 10 plagues and the splitting of the Red Sea or the one day of oil that lasted for eight days.
On Purim, we celebrate our deliverance from the evil Haman and the king’s decree to kill all the Jews, but also we are overflowing with Joy remembering that G-d is always with us—in good times and G-d forbid in the bad times–we are not afraid of anything (another indecisive election, the stock market downturn, our enemies, Coronavirus, etc.) knowing that He loves us and cares for us, and will deliver us in the old days and in the new. May the final deliverance soon be completed with the arrival of the Mashiach—and the hidden will become revealed like on Purim and the joy will be forever increased. Amen.
