Moses 4

 It is clear that there was never two plans proposed in our premortal existence.  There was always established eternal plan of the Father.  The Savior only proposes, being the right of the firstborn - 

"Here am I; send me.'  (2 Nephi 16:8)

And - 

...my Beloved Son, which was my Beloved and Chosen from the beginning, said unto me—Father, thy will be done, and the glory be thine forever."  (Moses 4:2)

But Lucifer proposed an alternate plan saying -

"...Behold, here am I, send me, I will be thy son, and I will redeem all mankind, that one soul shall not be lost, and surely I will do it; wherefore give me thine honor."  (Moses 4:1)

He would accomplish as he - 

"...sought to destroy the agency of man...  (Moses 4:3)

The Lord has defined equality as - 

"...every man according to his wants and his needs, inasmuch as his wants are just—"  (Doctrine and Covenants 82:17)

Obviously, agency, opportunity, and righteousness.  But the world is now pushing "equity" with the idea 

that outcomes are equal.  This sounds more like Satan's plan of control and destroying agency.
