“The Lord’s authorized servants repeatedly teach that one of the principal purposes of our mortal existence is to be spiritually changed and transformed through the Atonement of Jesus Christ. Alma declared:
” ‘Marvel not that all mankind, yea, men and women, all nations, kindreds, tongues and people, must be born again; yea, born of God, changed from their carnal and fallen state, to a state of righteousness, being redeemed of God, becoming his sons and daughters;
” ‘And thus they become new creatures; and unless they do this, they can in nowise inherit the kingdom of God’ (Mosiah 27:25-26).
“We are instructed to ‘come unto Christ, and be perfected in him, and deny [ourselves] of all ungodliness’ (Moroni 10:32), to become ‘new creature[s]’ in Christ (see 2 Corinthians 5:17), to put off ‘the natural man’ (Mosiah 3:19), and to experience ‘a mighty change in us, or in our hearts, that we have no more disposition to do evil, but to do good continually’ (Mosiah 5:2). Please note that the conversion described in these verses is mighty, not minor–a spiritual rebirth and fundamental change of what we feel and desire, what we think and do, and what we are. Indeed, the essence of the gospel of Jesus Christ entails a fundamental and permanent change in our very nature made possible through our reliance upon ‘the merits, and mercy, and grace of the Holy Messiah’ (2 Nephi 2:8). As we choose to follow the Master, we choose to be changed–to be spiritually reborn.”
