At the conclusion of the Savior’s visit among the Nephites, Mormon returned to what was a major theme of the Lord’s instructions among the people—that in the last days the Gentiles will reject the teachings of the Lord and grow rapidly in wickedness to their destruction (see 3 Nephi 16:10; 21:14–21). The writings in 3 Nephi seem to have had a profound effect upon Mormon. In his final testimony, Mormon revisited the Savior’s teachings and prophecies condemning the wicked and perverse and the pollutions and hypocrisies of the last days. In the last verses of 3 Nephi, Mormon offered the only antidote to these destructive conditions—come unto Jesus Christ and have faith in Him, repent of your sins, be baptized, and be filled with the Holy Ghost “that ye may be numbered with my people who are of the house of Israel” (3 Nephi 30:2).
