President Spencer W. Kimball, recorded in 1974, as he described the future of missionary work:
“I believe that the Lord is anxious to put into our hands inventions of which we laymen have hardly had a glimpse. …
“With the Lord providing these miracles of communication, and with the increased efforts and devotion of our missionaries and all of us, and all others who are ‘sent,’ surely the divine injunction will come to pass: ‘For, verily, the sound must go forth from this place into all the world, and unto the uttermost parts of the earth—the gospel must be preached unto every creature’ (D&C 58:64)” (“When the World Will Be Converted,” Ensign, Oct. 1974, 10–11).
In 1966 President David O. McKay prophesied scientific discoveries that “stagger the imagination” would make possible the preaching of the gospel to every kindred, tongue, and people. And further:
“Discoveries latent with such potent power, either for the blessing or the destruction of human beings, as to make man’s responsibility in controlling them the most gigantic ever placed in human hands. … This age is fraught with limitless perils, as well as untold possibilities” (in Conference Report, Oct. 1966, 4).
In 1981 President Gordon B. Hinckley taught: “We are confident that as the work of the Lord expands, he will inspire men to develop the means whereby the membership of the Church, wherever they may be, can be counseled in an intimate and personal way by his chosen prophet. Communication is the sinew that binds the Church as one great family. Between those facilities which are now available and those which are on the horizon, we shall be able to converse one with another according to the needs and circumstances of the time” (“Faith: The Essence of True Religion,” Ensign, Nov. 1981, 5).
