There are many lessons to be learned from the celebration of Sukkot, but from an overall perspective the grand lesson is that God intends His people to realize a life a joy, a joy that flows out of relationship with Him first of all, and then out of the relationships we have among family and friends. In fact, these relationships exemplify the Hebrew concept of “shalom,” for it is only when there is mutual respect and appreciation that a relationship can produce a full joy. A relationship fraught with the discord of selfishness or deceit is not one which produces joy, for there is no shalom.
– Tim Hegg on Sukkot
