The Lord declared, “Faith cometh not by signs, but signs follow those that believe” (D&C 63:9; see also verses 10–12). Elder Bruce R. McConkie (1915–85) explained that the righteous will have signs in their lives as a result of their faith:
“Signs flow from faith. They may incidentally have the effect of strengthening the faith of those who are already spiritually inclined, but their chief purpose is not to convert people to the truth, but to reward and bless those already converted. …
“Signs are sacred grants of divine favor reserved for the faithful and concerning which the recipients are commanded not to boast” (Mormon Doctrine, 2nd ed. [1966], 713–14).
