In the year AD 331, during the final phases of warfare between the Nephites and the Lamanites, Aaron, king of the Lamanites, brought an army of 44,000 against Mormon his 42,000. Mormon defeated Aaron and caused him to flee. For a time, Mormon rejoiced in the manifestation of repentance displayed by his countrymen. His joy was short-lived because the Nephites did not have a godly sorrow for sin. “And they did not come unto Jesus with broken hearts and contrite spirits, but they did curse God, and wish to die. Nevertheless they would struggle with the sword for their lives. And it came to pass that my sorrow did return unto me again, and I saw that the day of grace was passed with them, both temporally and spiritually”. That was around AD 345. Over the next period of time, Mormon and his people withstood the assaults of the Lamanites. “Nevertheless the strength of the Lord was not with us; yea, we were left to ourselves, that the Spirit of the Lord did not abide in us; therefore we had become weak like unto our brethren”. Some ten years later, the king of the Lamanites. Then followed a period of unprecedented violence and bloodshed, leading to the final battle at Cumorah around AD 385. Those Nephites who fled to the army of Aaron, as Moroni later reported, “have fallen victims to their the Lamanites’] awful brutality”. Thus ended the chronicles of warfare in the Book of Mormon, an abiding confirmation of the prophecy of Lehi, nearly a thousand years previous.
Wherefore, I, Lehi, have obtained a promise, that inasmuch as those whom the Lord God shall bring out of the land of [Jerusalem shall keep his commandments, they shall prosper upon the face of this land; and they shall be kept from all other nations, that they may possess this land unto themselves. And if it so be that they shall keep his commandments they shall be blessed upon the face of this land, and there shall be none to molest them, nor to take away the land of their inheritance; and they shall dwell safely forever.
But behold, when the time cometh that they shall dwindle in unbelief, after they have received so great blessings from the hand of the Lord—having a knowledge of the creation of the earth, and all men, knowing the great and marvelous works of the Lord from the creation of the world; having power given them to do all things by faith; having all the commandments from the beginning, and having been brought by his infinite goodness into this precious land of promise—behold, I say, if the day shall come that they will reject the Holy One of Israel, the true Messiah, their Redeemer and their God, behold, the judgments of him that is just shall rest upon them.
