“In the premortal council, it was pride that felled Lucifer, ‘a son of the morning.’ (2 Ne. 24:12–15; see also D&C 76:25–27; Moses 4:3.) …
“In the pre-earthly council, Lucifer placed his proposal in competition with the Father’s plan as advocated by Jesus Christ. (See Moses 4:1–3.) He wished to be honored above all others. (See 2 Ne. 24:13.) In short, his prideful desire was to dethrone God. (See D&C 29:36; 76:28.)” (Ezra Taft Benson, “Beware of Pride,”Ensign, May 1989, 4–5).
