And now, it came to pass that when king Benjamin had thus spoken to his people, he sent among them, desiring to know of his people if they believed the words which he had spoken unto them.
And they all cried with one voice, saying: Yea, we believe all the words which thou hast spoken unto us; and also, we know of their surety and truth, because of the Spirit of the Lord Omnipotent, which has wrought a mighty change in us, or in our hearts, that we have no more disposition to do evil, but to do good continually.-- Mosiah 5:1-2
At the October 1993 general conference, Elder Spencer J. Condie of the Seventy said, "One of the powerful doctrines of the Book of Mormon is that we can, indeed we must, undergo a mighty change of heart."
Elder Condie spoke of a friend who was reared in a family without the blessings of the gospel. "Through a series of unfortunate events in his early youth, he was introduced to homosexuality, and gradually he became a prisoner of this addictive behavior.
"One day two young missionaries knocked on his door and asked if he would be interested in learning of the restored gospel of Jesus Christ. In his heart of hearts he wanted to be freed from his prison of uncleanness, but feeling unable to change the direction his life had taken, he terminated the missionary discussions. Before leaving his apartment, the two elders left a copy of the Book of Mormon with him and testified of its truthfulness.
"My friend placed the book on his bookshelf and forgot about it for several years. He continued acting out his homosexual tendencies, assuming that such relationships would bring him happiness. But, alas, with each passing year, his misery increased.
"One day in the depths of despair, he scanned his bookshelf for something to read which might edify and uplift him and restore his self-worth. His eye caught hold of the book with a dark blue cover, which the missionaries had given him several years before. He began to read. On the second page of this book, he read of Father Lehi's vision in which he was given a book to read, and 'as he read, he was filled with the Spirit of the Lord.' (1 Nephi 1:12.) And as my good friend continued reading, he too was filled with the Spirit of the Lord.
"He read King Benjamin's benedictory challenge to undergo a mighty change of heart -- not a little change, but a mighty change. He was given hope by the comforting conversion stories of Enos, Alma, Ammon and Aaron. He was also inspired by the account of the Savior's visit to the ancient Nephites. By the time he reached the final page of the Book of Mormon, he was prepared to accept Moroni's loving invitation to 'come unto Christ, and be perfected in him, and deny yourselves of all ungodliness.' (Moroni 10:32.)
"My friend contacted the Church and was taught the gospel and was baptized. Within a relatively short time, he married a lovely young woman, and they are the parents of several beautiful children. He and his wife are very dynamic and committed servants of the Lord, influencing many others for good."
