Yesterday, as I was studying this week’s Parsha, Terumah, I was reminded of a fascinating feature of the Mishkan, the portable Sanctuary in which Hashem dwelled, accompanying the Israelites wherever they went. The altar, upon which sacrifices were offered, was made of copper. This raises an interesting question; why was the altar- a Holy place on which one offered donations to Hashem- made of a less precious metal, namely copper? Why wasn’t it made of gold or silver- metals which we know the Israelites possessed?
The answer lies in a central Jewish concept, namely teshuva. When copper tarnishes or becomes dirty, it can be wiped clean, effectively leaving behind a clean slate. Similarly, when we- the Jewish people- transgress, individually or together, we, too, can wipe away our sins and be left in a higher spiritual place than we were before.
In Biblical times, offerings were sacrificed on the copper alter as a form of teshuva, as well as as a regular donation to G-d. Today, we have no altar to make sacrifices on, but we can still do teshuva at any time or place. Rather than making daily sacrifices, we pray three times a day, and as ever, we can wipe away the sins and guilt of the past by making up for our mistakes.
Many people think that their mistakes define who they are. They believe that because they did something wrong, they are automatically a bad person and can’t be forgiven. But the mistakes we make always serve a purpose; teaching us to behave differently in the future. Just like the copper alter in the Mishkan, whenever we become tarnished or unclean, we can always wipe away our sins with true repentance. Repentence doesn’t just involve G-d, or those around us who we have wronged; it begins in one’s heart, with a resolution to do teshuva and become a better person.
As we are frequently reminded by Jewish wisdom, it’s better to sin and repent- and change!- than to never sin at all.
