Nephi’s first point is that the arrival of the penitent at the point immediately after baptism is an important work, but one in which they can take no personal glory, for it was the spirit moving in them that brought them to this point. The emphasis on Christ as “him who is mighty to save” indicates that this Nephite baptismal ritual has already transcended a simple ritual cleansing, and the Nephites understand the rite in the context of the removal of sin as well as ritual cleanness.
