“He Who is the Author of All Sin”

Joseph F. McConkie, Robert L. Millet
“Wherefore, because that Satan rebelled against me, and sought to destroy the agency of man, which I, the Lord God, had given him, and also, that I should give unto him mine own power; by the power of mine Only Begotten, I caused that he should be cast down; and he became Satan, yea, even the devil, the father of all lies, to deceive and to blind men, and to lead them captive at his will, even as many as would not hearken unto my voice (Moses 4:3-4, italics added; compare John 8:44).”
