There are two keys to productive missionary work -- (1) family-to-family friendshipping (when a member family shares the gospel with a nonmember family) and (2) cooperation between members and the missionaries to reach people...Every member knows of nonmembers he or she can refer to the missionaries. Every father, mother, and youth in this church should share the gospel by giving a Book of Mormon, telling the account of the Prophet Joseph Smith, or inviting our acquaintances to a special meeting.
