Salvation is a choice on the part of human beings and is only a reality at the time of personal conversion. The Book of Mormon states that “little children are alive in Christ, even from the foundation of the world,” which is tantamount to election, and implies that this election is reversed when a person sins, necessitating a restoration to a state of grace.
(II Nephi 10:23-24) “Therefore, cheer up your hearts, and remember that ye are free to act for yourselves — to choose the way of everlasting death or the way of eternal life. Wherefore, my beloved brethren, reconcile yourselves to the will of God, and not to the will of the devil and the flesh; and remember, after ye are reconciled unto God, that it is only in and through the grace of God that ye are saved.”
(Moroni 8:11) “And their little children need no repentance, neither baptism. Behold, baptism is unto repentance to the fulfilling the commandments unto the remission of sins. But little children are alive in Christ, even from the foundation of the world; if not so, God is a partial God, and also a changeable God, and a respecter to persons; for how many little children have died without baptism! Wherefore, if little children could not be saved without baptism, these must have gone to an endless hell.”
