In all these various dispensations God has directly spoken from the heavens; he has communicated his will to the human family. He has raised up revelators and inspired them, he has filled his servants with the spirit of prophecy, that they should foretell the future. He has inspired them to write revelations, and hence in all these different dispensations the God of heaven has thus authorized the children of men to build up his Zion on the earth, and without these no such thing as Zion can be built up among the children of men.
