This is the great promise to all those who inhabit this land of promise. It applied to those who lived before the flood. It applied to the Jaredites. It applied to the Nephites, Lamanites, and Mulekites. It applies to the current inhabitants of North and South America. It is repeated many times in the Book of Mormon because the people keep forgetting the promises of the Lord. Like the covenant given to the children Israel by Moses (Lev 26), this promise was associated with a blessing and a cursing. The history of the Book of Mormon shows the fulfillment of both portions of the promise. At times the people are prospered, at times they are cut off from the presence of the Lord. The Book of Mormon acts as a voice of warning for us--to remind us what happens to those who live on this land and neglect to keep the commandments.
