At a solemn assembly held in the Kirtland Temple on April 6, 1837, the Prophet Joseph Smith said, “After all that has been said, the greatest and most important duty is to preach the Gospel.”1
Almost precisely seven years later, on April 7, 1844, he declared: “The greatest responsibility in this world that God has laid upon us is to seek after our dead. The apostle says, ‘They without us cannot be made perfect’ [see Hebrews 11:40]; for it is necessary that the sealing power should be in our hands to seal our children and our dead for the fulness of the dispensation of times—a dispensation to meet the promises made by Jesus Christ before the foundation of the world for the salvation of man.”2
Some individuals may wonder how both preaching the gospel and seeking after our dead can be simultaneously the greatest duties and responsibilities God has placed upon His children. My purpose is to suggest that these teachings highlight the unity and oneness of the latter-day work of salvation. Missionary work and family history and temple work are complementary and interrelated aspects of one great work, “that in the dispensation of the fulness of times he might gather together in one all things in Christ, both which are in heaven, and which are on earth; even in him” (Ephesians 1:10).
I pray the power of the Holy Ghost will assist you and me as we consider together the marvelous latter-day work of salvation.
