President Marion G. Romney (1897–1988) of the First Presidency gave the following insight regarding the meaning of true conversion:
“Webster [dictionary] says the verb, ‘convert,’ means ‘to turn from one belief or course to another.’ That ‘conversion’ is ‘a spiritual and moral change. …’ As used in the scriptures, ‘converted’ generally implies not merely mental acceptance of Jesus and his teachings but also a motivating faith in him and in his gospel—a faith which works a transformation, an actual change in one’s understanding of life’s meaning and in his allegiance to God—in interest, in thought, and in conduct. …
“In one who is wholly converted, desire for things inimical [contrary] to the gospel of Jesus Christ has actually died, and substituted therefor is a love of God with a fixed and controlling determination to keep his commandments. …
“… From this it would appear that membership in the Church and conversion are not necessarily synonymous. Being converted … and having a testimony are not necessarily the same thing either. A testimony comes when the Holy Ghost gives the earnest seeker a witness of the truth. A moving testimony vitalizes faith; that is, it induces repentance and obedience to the commandments. Conversion, on the other hand, is the fruit of, or the reward for, repentance and obedience” (in Conference Report, Oct. 1963, 23–24).
