Justification for citing these scriptures in connection with our present consideration will be found in the cause of the great contention--the conditions that led to this war in heaven. It is plain from the words of Isaiah that Lucifer, already of exalted rank, sought to aggrandize himself without regard to the rights and agency of others. The matter is set forth, in words that none may misapprehend, in a revelation given to Moses and repeated through the first prophet of the present dispensation: "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. 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. 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."[10] Thus it is shown that prior to the placing of man upon the earth, how long before we do not know, Christ and Satan, together with the hosts of the spirit-children of God, existed as intelligent individuals,[11] possessing power and opportunity to choose the course they would pursue and the leaders whom they would follow and obey.[12] In that great concourse of spirit-intelligences, the Father's plan, whereby His children would be advanced to their second estate, was submitted and doubtless discussed. The opportunity so placed within the reach of the spirits who were to be privileged to take bodies upon the earth was so transcendently glorious that those heavenly multitudes burst forth into song and shouted for joy.[13] Satan's plan of compulsion, whereby all would be safely conducted through the career of mortality, bereft of freedom to act and agency to choose, so circumscribed that they would be compelled to do right--that one soul would not be lost--was rejected; and the humble offer of Jesus the First-born--to assume mortality and live among men as their Exemplar and Teacher, observing the sanctity of man's agency but teaching men to use aright that divine heritage--was accepted. The decision brought war, which resulted in the vanquishment of Satan and his angels, who were cast out and deprived of the boundless privileges incident to the mortal or second estate.
