The scriptures certify that “faith cometh not by signs, but signs follow those that believe. Yea, signs come by faith, not by the will of men, nor as they please, but by the will of God.” (D&C 63:9-10.) Unfortunately, even in the true Church there are occasionally those who become caught up in a way of thinking which partakes of the spirit of sign seeking.
“It is a wicked and adulterous generation,” repeated President Joseph F. Smith, “that seeketh after a sign.Show me Latter-day Saints who have to feed upon miracles, signs and visions in order to keep them steadfast in the Church, and I will show you members of the Church who are not in good standing before God, and who are walking in slippery paths. It is not by marvelous manifestations unto us that we shall be established in the truth, but it is by humility and faithful obedience to the commandments and laws of God.
When I as a boy first started out in the ministry, I would frequently go out and 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, precept upon precept, here a little and there a little, 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.” (Gospel Doctrine, p. 7.)
