One of the Three Witnesses of the Book of Mormon
Testimony of Joseph Smith
“Do I believe it! Do you see the sun shining! Just as surely as the sun is shining on us and gives us light, and the [moon] and stars give us light by night, just as surely as the breath of life sustains us, so surely do I know that Joseph Smith was a true prophet of God, chosen of God to open the last dispensation of the fulness of times; so surely do I know that the Book of Mormon was divinely translated. I saw the plates; I saw the Angel; I heard the voice of God. I know that the Book of Mormon is true and that Joseph Smith was a true prophet of God. I might as well doubt my own existence as to doubt the divine authenticity of the Book of Mormon or the divine calling of Joseph Smith” (in William Harrison Homer, “The Passing of Martin Harris,” Improvement Era, Mar. 1926, 470).
