“Elder John A. Widtsoe taught that evidence can remove honest doubt and give assurances that build faith. ‘After proper inquiries, using all the powers at our command,’ he said, ‘the weight of evidence is on one side or the other. Doubt is removed.’ ‘Doubt of the right kind—that is, honest questioning—leads to faith’ and ‘opens the door to truth,’ for where there is doubt, faith cannot thrive [Evidences and Reconciliations, 28–29]. Elder Joseph Fielding Smith likewise affirmed that evidence, as convincing as in any court in the land, proves ‘beyond the possibility of doubt that Joseph Smith and Oliver Cowdery spoke the truth’ [Doctrines of Salvation, 2:124]” (Welch, “Power of Evidence in the Nurturing of Faith,” 155).
