Have you ever read the Book of Mormon and prayed about it?
Yes, I've read the entire Book of Mormon, as well as the other LDS Scriptures--the Doctrine & Covenants and the Pearl of Great Price. I continue to read through these works, and I have sincerely prayed (and continue to sincerely pray) about all of them. I take it for all sorts of reasons that God told me that He's not the author of them (these reasons will become obvious to you as you look around my site). To quote the Book of Mormon, God has indeed "manifest[ed] the truth of it unto... [me], by the power of the Holy Ghost" (Moroni 10:4). The truth is that the LDS Scriptures are not of God!
