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 missionaires 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. Repeated requests and suggestions that it be printed have influenced the decision to enlarge upon the original outline and have it published in book form. It is here presented under the title "A Marvelous Work and A Wonder."
