Speaking of Adam’s baptism, we read the following:
And thus he was baptized, and the Spirit of God descended upon him, and thus he was born of the Spirit, and became quickened in the inner man. (Moses 6:65)
In this one verse, we have one of, if not the, most explicit witness to baptismal regeneration in uniquely Latter-day Saint works—here, in this passage, through the instrumentality of water baptism, the Holy Spirit quickens (makes alive) the inner man, and thus one is “born of the Spirit” (i.e., regenerated).
