The Origin and Purpose of the Book of Mormon Phrase “If Ye Keep My Commandments Ye Shall Prosper in the Land”

We are told in the Title Page of the Book of Mormon that the Book of Mormon was revealed in our day “to show unto the remnant of the house of Israel what great things the Lord hath done for their fathers; and that they may know the covenants of the Lord, that they are not cast off forever.” Hence, the covenantal context, structure, and logic of the Book of Mormon demand further consideration, exploration, and elucidation. A prosperous starting point is the phrase “If ye keep my commandments ye shall prosper in the land.” This covenantal phrase is used throughout the Book of Mormon as a summary of the theological logic of the suzerain-vassal treaty covenant type in which God sought to secure the fidelity of his people, who would receive in exchange continued prosperity in His appointed promised lands.
