Elder Dallin H. Oaks of the Quorum of the Twelve Apostles spoke of the dangers accompanying the seeking of signs for faith:
“The showing of a sign can work to the condemnation of those who are brought to knowledge by that means. They miss the opportunity to develop faith, and they subject themselves to a more severe punishment for backsliding than those whose spiritual development is proceeding along the normal pathway of developing faith.
“There are other ‘condemnations’ to those who seek signs without first developing the faith God has required as a prerequisite.
“One condemnation is to be misled. God warned ancient Israel against following prophets who gave signs and wonders and then sought to lead them away to the worship of strange gods. (Deut. 13:1–3.) The Savior taught his apostles that in the last days ‘there shall also arise false Christs, and false prophets, and shall show great signs and wonders, insomuch that, if possible, they shall deceive the very elect, who are the elect according to the covenant.’ (JST Matt. 24:23; also see Matt. 24:24; Mark 13:22.) …
“… In our day, God does not use miracles or signs as a way of teaching or convincing the unbeliever. As a result, we should not ask for signs for this purpose, and we should be deeply suspicious of the so-called spiritual evidences of those who do” (The Lord’s Way [1991], 85–86).
