One of the core foundational elements of teshuva is the formula of the Thirteen Attributes. It is said in the build up to and the culmination of Yom Kippur.
The Gemara cryptically allegorises that in order to teach them to Moshe, Hashem put on a Tallis like a chazan and shliach tzibbur – a prayer leader. In this guise, Hashem instructed Moshe that if people said the Thirteen Attributes, forgiveness would be abundant.
But why does the allegory need God to dress up in order to forgive us?
R’ Moshe Einstadter explains that the function of the shliach tzibbur (literally – agent of the community) is to enable those who don’t know how to join in. People who don’t know how are dependent on people who do in order to participate.
But this is a one-way relationship – the chazzan does not need an audience to pray – he can do it perfectly well on his own.
Yet should people have need of him, he can take on a greater role and responsibility than otherwise.
The same relationship exists between man and God.
We can’t help ourselves. When we make mistakes, why should teshuva make a difference? Should feeling bad suddenly make right wrong actions?
Yet the allegory offers a powerful resolution.
Hashem can be our shliach tzibbur. And so He gives us this formula for teshuva. Because we need Him to.
