“I am very grateful that the Latter-day Saints all over the world have a personal, individual and abiding testimony of the divinity of the work in which we are engaged. But for that testimony men would not think, or women either, of making the marvelous sacrifices that they do make at home and abroad, for the advancement of the work of the Lord” (Teachings of Presidents of the Church: Heber J. Grant, p. 68).
