Srm,
You are twisting "From this time forth, Joseph continued to receive instructions from the Lord" and "He would describe the ancient inhabitants of this continent, their dress, mode of travelling, and the animals upon which they rode; their cities, their buildings, with every particular; their mode of warfare; and also their religious worship. "
into "From this time forth, Josept continued to receive revelations about the ancient inhabitants of this continent, their dress, mode of travelling, and the animals upon which they rode; their cities, their buildings, with every particular; their mode of warfare; and also their religious worship. "
Nowhere does it indicate that this is the case.
