Cain to rule over Satan
Now as to whether or not those who in mortal life rebel and become sons of perdition will be able to exercise greater dominion than those who followed Lucifer, who became the devil and arch-enemy of Jesus Christ, might be a moot question. However, the Lord has made it definitely clear that Cain will hold that ascendancy in the realm of wickedness; that Satan desired to have him, and the implication is clear that the reason was because Cain had a body of flesh and bones. These are the words of the Lord on the subject: [He then quotes Moses 5:18-26)
As far as Cain is concerned, the information given is definite that he became Perdition, and that Lucifer who is Satan, became subject to him. It appears that the reason Satan desired to have him was due to the fact that Cain had obtained a body of flesh and bones and therefore had superior power, and Satan was willing to accept and be obedient to him because of that condition. The natural conclusion is, therefore, that a devil with a body of flesh and bones has some power greater than one who was denied the physical body. 1
“Both Satan and Cain bear the title father of lies, both having been liars from the beginning. (2 Ne. 9:9; Moses 5: 18-27.) The name signifies authorship and sponsorship of all that is dishonest and which leads away from the truth. In a similar sense Satan is the master of sin (Mosiah 4:14) and the father of secret combinations and every evil thing. (2 Ne. 26:22; Hela. 6:26; Moro. 7:12.)” 2
“Two persons, Cain and Satan, have received the awesome name-title Perdition. The name signifies that they have no hope whatever of any degree of salvation, that they have wholly given themselves up to iniquity, and that any feeling of righteousness whatever has been destroyed in their breasts. Both had great administrative ability and persuasive power in pre-existence, but both were rebellious and iniquitous from eternity. (D. & C. 76:25-27; 2 Ne. 2:17-18.) Both came out in open rebellion against God having a perfect knowledge that their course was contrary to all righteousness. Satan was denied a tabernacle for his spirit body, but Cain has gained one, and as a consequence has a position of pre-eminence over the devil. To Cain the Lord said: “Satan desireth to have thee; and it shall be unto thee according to his desire. And thou shalt rule over him; For from this time forth thou shalt be the father of his lies; thou shalt be called Perdition; for thou wast also before the world.” (Moses 5:18-25.)” 3
“Being subject to law, and having their agency, all the spirits of men, while yet in the Eternal Presence, developed aptitudes, talents, capacities, and abilities of every sort, kinds, and degree. During the long expanse of life which then was, an infinite variety of talents and abilities came into being. As the ages rolled, no two spirits remained alike. Mozart became a musician; Einstein centered his interest in mathematics; Michelangelo turned his attention to painting. Cain was a liar, a schemer, a rebel who maintained a close affinity to Lucifer. Abraham and Moses and all of the prophets sought and obtained the talent for spirituality. Mary and Eve were two of the greatest of all the spirit daughters of the Father. The whole house of Israel, known and segregated out from their fellows, was inclined toward spiritual things. And so it went through all the hosts of heaven, each individual developing such talents and abilities as his soul desired. The Lord endowed us all with agency; he gave us laws that would enable us to advance and progress and become like him; and he counseled and exhorted us to pursue the course leading to glory and exaltation. He himself was the embodiment and personification of all good things. Every desirable characteristic and trait dwelt in him in its eternal fulness. All of his obedient children started to become like him in one way or another. There was as great a variety and degree of talent and ability among us there as there is among us here. Some excelled in one way, others in another. The firstborn excelled all of us in all things.” 4
