God has promised that in our present day, He will restore the descendants of Israel (Jacob) “to the true church and fold of God” (2 Nephi 9:2). Every person who joins the Church of Jesus Christ is either a literal blood descendant of Israel or becomes adopted by the Lord as if they were. So when you seek to share the Gospel, you are seeking only to restore the House of Israel to the blessings that Israel’s family once enjoyed.
One of the reasons the Lord gave the prophet Joseph Smith to the world “for a covenant of the people” was to bring back truths and priesthood keys that had been lost through wickedness and faithlessness. These truths and keys are necessary in order for a church to have the power to carry out the divine promise to gather Israel for the second time.
So the Lord put these truths and keys into The Church of Jesus Christ of Latter-day Saints. In 1836, the ancient prophet Moses appeared to Joseph Smith and Oliver Cowdery and “committed unto [them] the keys of the gathering of Israel from the four parts of the earth.” So Mormons, or Latter-day Saints (LDS), believe that we have been selected to lead the global effort to put the jigsaw puzzle of the House of Israel back together.
That’s just the tip of the iceberg. What do you think – why else is the house of Israel relevant to latter-day missionary efforts?
