This study sought answers to two major questions regarding the Book of Mormon prophets: first, did a prophet's unique personality cause him to be significantly qualified and effective in coping with the problems of his ministry; and second, were a prophet's teachings directly relevant to his problems, assisting him to be effective in fulfilling his assignments. Six minor hypotheses were used to gather data regarding the four representative prophets chosen: Lehi, Nephi, Alma the Younger, and Mormon. The teachings studied were limited to those which reached the ears of a prophet's contemporaries, and were further limited to those which were clearly emphasized in at least one verse. The minor hypotheses yielded abundant and clear evidence showing that in all but one problem (one in Lehi's life) the prophets were qualified and effective in meeting their problems. The evidence also demonstrated that all of the teachings which were studied were directly relevant and supportive in solving the given problems.
