BD War in Heaven
This term arises out of Rev. 12:7 and refers to the conflict that took place in the premortal existence among the spirit children of God. The war was primarily over how and in what manner the plan of salvation would be administered to the forthcoming human family upon the earth. The issues involved such things as agency, how to gain salvation, and who should be the Redeemer. The war broke out because one-third of the spirits refused to accept the appointment of Jesus Christ as the Savior. Such a refusal was a rebellion against the Father’s plan of redemption. It was evident that if given agency, some persons would fall short of complete salvation; Lucifer and his followers wanted salvation to come automatically to all who passed through mortality, without regard to individual preference, agency, or voluntary dedication (see Isa. 14:12-20; Luke 10:18; Rev. 12: 4-13 ; D&C 29:36-38; Moses 4:1-4). The spirits who thus rebelled and persisted were thrust out of heaven and cast down to the earth without mortal bodies, “and thus came the devil and his angels” ( D&C 29:37; see also Rev. 12:9; Abr. 3:24-28).
Moses 4
1 AND I, the Lord God, spake unto Moses, saying: That Satan, whom thou hast commanded in the name of mine Only Begotten, is the same which was from the beginning , and he came before me, 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.
2 But, behold, 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.
3 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;
4 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.
Abraham 3
22 Now the Lord had shown unto me, Abraham, the intelligences that were organized before the world was; and among all these there were many of the noble and great ones;
23 And God saw these souls that they were good, and he stood in the midst of them, and he said: These I will make my rulers; for he stood among those that were spirits, and he saw that they were good; and he said unto me: Abraham, thou art one of them; thou wast chosen before thou wast born.
24 And there stood one among them that was like unto God, and he said unto those who were with him: We will go down, for there is space there, and we will take of these materials, and we will make an earth whereon these may dwell ;
25 And we will prove them herewith, to see if they will do all things whatsoever the Lord their God shall command them;
26 And they who keep their first estate shall be added upon; and they who keep not their first estate shall not have glory in the same kingdom with those who keep their first estate; and they who keep their second estate shall have glory added upon their heads for ever and ever.
27 And the Lord said: Whom shall I send? And one answered like unto the Son of Man: Here am I, send me. And another answered and said: Here am I, send me. And the Lord said: I will send the first.
28 And the second was angry, and kept not his first estate; and, at that day, many followed after him.
