God has fulfilled and continues to fulfill Lehi’s promise of mercy to Laman’s and Lemuel’s children. There are several cases in the Book of Mormon where Lehi’s promise to the children of Laman and Lemuel were fulfilled (see Alma 17–26; Helaman 5–6; 13–15). In the latter days God has continued to fulfill Lehi’s promise of mercy to Laman and Lemuel’s children. President Henry B. Eyring of the First Presidency explained:
“Our faithful effort to offer to our family the testimony we have of the truth will be multiplied in power and extended in time.
“We have all seen evidence of that in families we have known. I saw it in South America as I looked into the faces of missionaries. Hundreds of them passed by me, shaking my hand and looking deeply into my eyes. I was nearly overwhelmed with the confirmation that these children of Father Lehi and of Sariah were there in the Lord’s service because our Heavenly Father honors His promises to families. To nearly his last breath, Lehi taught and testified and tried to bless his children. Terrible tragedy came among his descendants when they rejected his testimony, the testimonies of other prophets, and of the scriptures. But in the eyes and faces of those missionaries I felt confirmation that God has kept His promises to reach out to Lehi’s covenant children and that He will reach out to ours” (in Conference Report, Apr. 1996, 88; or Ensign, May 1996, 64).
