The Sfas Emes teaches that the People of Israel were in mourning over their actions that resulted in the Golden Calf. And now that they had repented and done teshuva, The Holy Blessed One, in all of His mercy, gave them the commandment/mitzvah of giving generously for the sake of the mishkan in order to make them happy. As it says in the Talmud, all mitzvot that were accepted joyously, are still done joyously to this day.
Maintaining relationships is difficult. Especially if there has been a fracture. Our involvement in the Golden Calf greatly hurt God, and when we reflected on what we had done, we needed to ask forgiveness in order to mend our union. However, that is only the beginning. In my experience, saying sorry is only one part of the process towards renewed trust and engagement. It takes positive interactions after having a fight with somebody to normalize the relationship again; to remind all parties about why they got together in the first place. Practically, this may mean trying to get somebody to laugh and smile after a conflict has been resolved. It will soften the heart and bring back positive feelings.
The same is true with our relationship with God. It makes sense that we would still be walking on eggshells after what we did with the Golden Calf. That is why it is so wonderful to appreciate the kindness done to us by God in giving us the opportunity to give of ourselves with a generous and open heart. After we atoned for our mistakes on Yom Kippur, we are immediately given the holiday of Sukkot, on which God commands us to be happy. As the Sfas Emes explains, the work of the mishkan and the holiday of Sukkot are ultimately the same matter. The joy that one experiences in serving God after teshuva is an everlasting joy.
Service performed from a place of fear and obedience may be important and serve a purpose. And this week we are reminded that fear is often not a long-lasting motivator. Happiness, fun and camaraderie are what sinks roots into the hearts and minds of a person. This week let us continue the ecstatic work of creating holy spaces in our communities. Our joy creates the ideal dwelling place for the Divine Presence/Shekhina. And that delightful dwelling place will be an everlasting structure.
