Russell M. Nelson taught,

“Every person so baptized who receives the gift of the Holy Ghost, which seals the ordinance, is under solemn covenant with the Lord to obey his commandments. Caring for the poor is one of those commandments. Surely, in Book of Mormon times, members of the Church had a sacred obligation to care for the poor.”
