There are two types of Nephites, those who are stiffnecked and those who have faith. Jarom understands that those who have faith will follow the commandments, and that they are also those who are following the particular brand of Mosaic law that Nephi taught at the end of his reign, and which was continued by Jacob and Enos. We understand this particularly from the reference to the Holy Spirit, a part of the teaching that is attached to the particularly Christian type of Messianism that was taught to the Nephites.
