This guide examines a wide variety of scriptural passages that cast light on the Last Days, the Second Coming of Jesus Christ, the Millennium, and the end of the world. It retells events surrounding the Second Coming of Christ, mainly through the Standard Works of the Church of Jesus Christ of Latter-day Saints-the Bible, the Book of Mormon, the Doctrine and Covenants, and the Pearl of Great Price-but also through archaeological, historical, and statistical sources. It is a compilation of posts from the blog "Put on the Armor of Light," written between September 2014 and November 2015.
