The sukkah itself represents the idea of the Jewish faith….
One who fulfills the mitzvah of sukkah actually becomes a partner with God and creation.
When we build the walls, this represents man’s effort. And man’s part in what he came into this world to accomplish…
The roof represents God’s providence, God’s help… We have to realize that we are not alone in this world; we are in it together with Hashem.
God says to you, ‘You go out there, and you try, you make an effort, you plant a seed, and I’ll be there to make everything work out in the end. I’m there with you.’
So the Jewish faith that God showed us in the desert is that we have to do our part, and we have to trust in Hashem to do His part.
