[Speaking of the latter-day Lamanites] “They do suffer from an inferiority complex that is well-nigh annihilating. Prisoners of war, slaves, and downtrodden people usually develop such a complex. But give them comparable education and opportunity with their non-Indian brother, acceptance and brotherly love by him, and they will emerge a rejuvenated people… . The chasm between what he is and what he will be is opportunity It is ours to give… . The Lamanites have believing blood, as evidenced by the words from the sixth chapter of Helaman” [verse 36]. (Spencer W. Kimball, Conference Report, Apr. 1949, pp. 105-106)
“I have asked for increased effort in the missionary work among the Lamanites, and I have been most gratified by the response. The missions in the Lamanite areas are the most active and most productive of all, with many more converts per missionary than in any of the other missions. It is as in days of old: [Hel. 6:36]. We have many Lamanite missionaries in the field now, and there will be many, many more, I am sure.” (Spencer W. Kimball, Ensign, Dec. 1975, p. 7)
“The converted Lamanite is devout. Few ever apostatize. Some lose their way as they partake of the worldliness about them, but generally the children of Lehi of the twentieth century have inherited that grace and ability to believe like their ancestors of the long ago (Hel. 6:36).” (Teachings of Spencer W. Kimball , p. 178)
