The Lord has declared that missionary work is the responsibility of all who follow Him. Members of the Lord’s Church can, by the goodness of their lives and the strength of their testimonies, share the gospel message and help prepare family members, friends, and other acquaintances who are not Latter-day Saints to be taught by the full-time missionaries.
When we experience the blessings of gospel living, we naturally want to share those blessings with others. The Lord spoke of the joy that comes into our lives when we share His gospel:
“If it so be that you should labor all your days in crying repentance unto this people, and bring, save it be one soul unto me, how great shall be your joy with him in the kingdom of my Father!” (D&C 18:15) …
Missionary work also includes helping and supporting those who join the Church. As instructed by President Gordon B. Hinckley, each new member of the Church needs three things: a friend, a responsibility, and nurturing with “the good word of God” (Moroni 6:4)
“[The work of salvation] would include the gathering of Israel through temple and family history work, working with families and individuals in need, and helping the missionaries to bring souls to Jesus Christ.”
