“It is an eternal principle that the powers of heaven are inseparably connected with righteousness (D&C 121:36). The working of miracles in the name of Jesus is an evidence that one is ‘cleansed every whit from his iniquity’ and thus worthy of the companionship of the Holy Ghost and the powers of God. The wonders of God—the signs and miracles which always attend a dispensation of the gospel—require righteousness in the human instrument (see D&C 50:27–30)” (McConkie et al., Doctrinal Commentary, 4:35).
