LeGrand Richards — The Inspired "Blueprint" of the Restoration

While serving as the President of the Southern States Mission, LeGrand Richards was inspired to develop a systematic teaching method known as the "Message of Mormonism." He recounts how the Holy Ghost guided him to organize biblical scriptures into a "blueprint" of the true Church of Christ. He used this blueprint to challenge investigators and ministers to find any other church that matched the biblical pattern of prophets, apostles, and revelation. This inspired framework became the foundation for his book, "A Marvelous Work and a Wonder," and led to numerous conversions by demonstrating the logical necessity of the Restoration.

Fuller account of this event (as retold in A Marvelous Work and a Wonder - Brigham Young University - OverDrive):

At the conclusion of Elder LeGrand Richards' presidency of the Southern States Mission of The Church of Jesus Christ of Latter-day Saints in 1937, he left with the missionaries an outline entitled "The Message of Mormonism." This outline was prepared to assist the missionaries in their study and presentation of the gospel in a systematic and logical manner. It has since been used in a number of missions and by stake missionaries. Due to its strong influence on missionary work, it was later decided to enlarge upon the original outline and have it published as a book under the title "A Marvelous Work and A Wonder."
