Heber J. Grant
"I rejoice exceedingly in the Gospel of Jesus Christ that has been revealed in this day, and I earnestly desire that I may be able, in connection with the rest of the Latter-day Saints, to so order my life that my mind may never become darkened, that I may never depart from the truth, or break any of the covenants which I have made with the Lord" (Teachings of Presidents of the Church: Heber J. Grant, p. 26).
