“Let me promise you here today that if the Latter-day Saints will honestly and conscientiously from this day forth, as a people, keep the monthly fast and pay into the hands of their bishops the actual amount that they would have spent for food for the two meals from which they have refrained; and if in addition to that they will pay their honest tithing, it will solve all of the problems in connection with taking care of the Latter-day Saints. We would have all the money necessary to take care of all the idle and all the poor.Every living soul among the Latter-day Saints that fasts two meals once a month will be benefited spiritually and be built up in the faith of the gospel of the Lord Jesus Christ--benefited spiritually in a wonderful way--and sufficient means will be in the hands of the bishops to take care of all the poor.”
