"I daily went into the attic story of the Temple," wrote Heber C. Kimball, "and poured out my soul unto the Lord, asking his protection and power to fulfill honorably the mission appointed me." Heber found the reassurance he sought. "Hyrum, . . . when he would talk about my mission, wept like a little child," Heber recalled. "He was continually blessing and encouraging me, and pouring out his soul in prophecies upon my head. He said to me, 'Go, and you shall prosper as not many have prospered' " (Millennial Star, Sept. 10, 1864, 585; Sept. 17, 1864, 598).
The efforts of the Twelve and their associates were remarkably successful. By 1841 more than 6,000 people from the British Isles had joined the Church. By 1879 more than 38,000 British converts had immigrated to America, giving much needed strength to the Church.
As with Heber C. Kimball, the Lord continues to call His missionaries through his appointed servants. "Who sends them?" asked Lorenzo Snow regarding missionaries. "The God of Israel sends them. It is His work. There is no mortal man that is so much interested in the success of an elder when he is preaching the Gospel as the Lord that sent him to preach to the people who are the Lord's children" (Millennial Star, July 16, 1894, 451).
