Alma, after uttering this prophecy, disappeared in the same mysterious way that Moses did, and no man knoweth his grave unto this day. At this period all who believed in Christ took upon them the name of Christians. Various wars now raged between the Lamanites and Nephites. The people of Nephi erected many forts and high mounds to secure themselves from the invasion of their enemies. The Book of Helaman, which consists of five chapters, opens with the fortieth year of the reign of the Judges. It details sad accounts of dissensions and war, and strange alternations of prosperity and adversity to the church. A man by the name of Nephi, who was now chief judge, imitated Alma, and laying down his civil office, became a great preacher and prophet, performing miracles and mighty wonders. He went even to the Lamanites, and was so successful in converting them, that he arrested the tide of war and restored peace to the land. The earth shook, the heavens were opened, and angels came down at his voice. After Nephi, rose up Samuel, a Lamanite, who predicted that Christ would come in five years, and that on the day he was born, though the sun would go down as usual, there would be no night, it would continue as light as day. This was to be the sign. Another sign to attend his death, which was to take place in the thirty-fourth year after his birth, was three whole days of darkness, in which there were to be thunderings and lightnings, and earthquakes, and the rending of rocks and cleaving of hills. According to the testimony in the next book, at the end of five years the sign of his birth occurred, two days succeeding each other without any intervening night. The Nephites, therefore, knew that Christ had come. They accordingly reckoned their time from this period, regarding it as the commencement of a new era. The Lamanites that were converted now became white as the Nephites. At the end of thirty-three years, the signs that were foretold would accompany the death of Christ, appeared. There was a great tempest, and terrible thunder; the earth shook, as though about to divide asunder. Vivid lightning ran along on the ground, cities were overturned and buried in the midst of the sea--a terrible darkness came over the land for three days--and a great mourning and howling and weeping among the people. The voice of Christ was heard, amid the awful tempest, denouncing woes upon sinners, and offering grace and salvation to all who would repent and believe. After this Christ made his personal appearance on the earth, coming down from heaven with great glory. There were several occasions on which he appeared, at which times he delivered to the assembled thousands all the instruction, and performed nearly all the miracles recorded in the New Testament, and then he was again taken up out of their sight. He ordained twelve apostles and gave them singular gifts. He instituted baptism and the Lord's supper,
