"President Joseph F. Smith explained how this pattern of revelation occurred in his life: “As a boy … I would frequently … ask the Lord to show me some marvelous thing, in order that I might receive a testimony. But the Lord withheld marvels from me, and showed me the truth, line upon line … , until He made me to know the truth from the crown of my head to the soles of my feet, and until doubt and fear had been absolutely purged from me. He did not have to send an angel from the heavens to do this, nor did He have to speak with the trump of an archangel. By the whisperings of the still small voice of the spirit of the living God, He gave to me the testimony I possess. And by this principle and power He will give to all the children of men a knowledge of the truth that will stay with them, and it will make them to know the truth, as God knows it, and to do the will of the Father as Christ does it. And no amount of marvelous manifestations will ever accomplish this” (in Conference Report, Apr. 1900, 40–41)."
"In many of the uncertainties and challenges we encounter in our lives, God requires us to do our best, to act and not be acted upon (see 2 Nephi 2:26), and to trust in Him. We may not see angels, hear heavenly voices, or receive overwhelming spiritual impressions. We frequently may press forward hoping and praying—but without absolute assurance—that we are acting in accordance with God’s will. But as we honor our covenants and keep the commandments, as we strive ever more consistently to do good and to become better, we can walk with the confidence that God will guide our steps. And we can speak with the assurance that God will inspire our utterances. This is in part the meaning of the scripture that declares, “Then shall thy confidence wax strong in the presence of God” (D&C 121:45)."
