The Conversion of William Morley Black: A Pioneer's Witness of the Book of Mormon (Ohio, 1849)

William Morley Black was born in Vermillion, Ohio, on February 11, 1826. As a young man seeking truth, he became increasingly dissatisfied with the religious sects of his day, feeling they lacked the authority and power of the biblical church. In the late 1840s he encountered missionaries of The Church of Jesus Christ of Latter-day Saints and began a sincere investigation of their claims, focusing particularly on the Book of Mormon.

In his autobiographical sketch, Black recounts taking the Book of Mormon into a secluded, quiet place to read and pray earnestly about its truthfulness. As he poured out his heart to God, asking for divine direction, he experienced a profound spiritual manifestation—a feeling of pure light, warmth, and peace that filled his mind and heart with absolute certainty that the Book of Mormon was a divine ancient record and that Joseph Smith was a true prophet called of God. This powerful witness of the Holy Ghost removed every doubt.

Acting immediately, Black was baptized in 1849. He gathered with the Saints, crossed the plains to the Salt Lake Valley as a pioneer, and helped settle the rugged San Juan region of southern Utah, leaving a legacy of faith. His conversion stands as a classic pioneer testament to the power of the Holy Ghost in confirming the truth of the restored gospel.
