Your question invites pondering.
The term “conversion” seems to point to two experiences. The first has to do with the experience of finding the truth and then allowing that experience to lead a person into the Church. The second follows. It consists of becoming so deeply moved spiritually that individuals seek that their “hearts may be purified” and they turn their backs permanently on sin (Mosiah 4:1-3).
The term “born again” is essentially the second definition for “conversion.” Perhaps we can think of “born again” as pointing to the results of conversion: “I have repented of my sins, and have been redeemed of the Lord,” declares Alma (Mosiah 27:24; emphasis added).
You might consult Ed J. Pinegar’s “Born of God” and Kay H. Smith’s “Conversion” in the Encyclopedia of Mormonism (Macmillan, 1992). You can find the electronic copy of the Encyclopedia at eom.byu.edu.
