" fasting, with prayer as its companion, is designed to increase spirituality; to foster a spirit of devotion and love of God; to increase faith in the hearts of men, thus assuring divine favor; to encourage humility and contrition of soul; to aid in the acquirement of rightousness; to teach man his nothingness and dependence upon God; and to hasten those who properly comply with the law of fasting along the path to salvation.
