Becoming a member of the Church of Jesus Christ of Latter-day Saints is an individual choice. We become members by being taught fundamental doctrines and principles and then by being baptized. Two missionaries share short lessons covering 1) How our church came about – called the Restoration; 2) Our purpose in life – called the Plan of Salvation; 3) Basic principles – Faith, Repentance, Baptism, and the Holy Ghost; and 4) Basic Commandments: The Ten Commandments, Law of Chastity, Word of Wisdom, and Tithes and Fast Offerings. The missionaries will also give them a copy of the Book of Mormon to read and study along with the Bible on their own. At some point during the missionaries’ lessons, they will ask everyone to take the time to pray about what they’ve learned and ask God whether it is truly from Him.
After a person receives an answer to their prayers that the Church of Jesus Christ of Latter-day Saints is Christ’s church, they are invited to be baptized. They’ll meet with another missionary to have a ‘baptismal interview’, which just means the missionary will talk to them, make sure they’ve been taught everything in the lessons (listed above), and that they understand what they’ve been taught and are ready to be baptized.
