Serving others at the Feast is vital to the purpose of observing it because, in addition to God blessing them through our own action, we are practicing God's way. It is through this obedient thinking/doing/living God's way of outgoing love and concern that He creates His obedient children in His spiritual image. Through living His "Way of Give" at the Feast we come to know God, and we come to be His spiritual children (Matthew 5:45). Serving others is a vital key to keeping a spiritual Feast!
