The Spirit brings certitude and conviction and banishes the darkness of doubt. Cyprian, a great defender of the faith after the apostolic period, spoke of his own conversion. “Into my heart,” he recounted, “purified of all sin, there entered a light which came from on high and then suddenly, and in a marvelous manner, I saw certainty succeed doubt” (cited by Harold B. Lee in Stand Ye in Holy Places, p. 57). “To know God our Eternal Father and Jesus Christ, whom he sent,” President Marion G. Romney explained, “one must, as did the Apostles of old, learn of them through the process of divine revelation. One must be born again.” (CR, October 1981, pp. 18, 20.)
