In the writings of Moses, as revealed to Joseph Smith, the matter is made still more clear. There we have an account of Satan appearing before Moses, and of his seeking to induce that faithful man to worship him instead of God; but Moses rebuked him in the name of the Lord Jesus, and afterwards the Lord appeared unto him and said: "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 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 Satan rebelled against me [his plans being rejected, as we have already seen], 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."[B] [Footnote B: Pearl of Great Price, p. 9.] From this we learn the cause of Lucifer's rejection and rebellion--his plan for man's redemption was of such a character that it would have destroyed the agency of man, and robbed God of his honor; and because that plan was rejected, he rebelled against God and was cast out of heaven. This was before the creation of the earth, and this controversy about which the rebellion took place was in relation to the plan of salvation--the gospel. These things were revealed to the Prophet Joseph, and they throw a perfect flood of light upon the scriptures which refer to Christ as the "Lamb slain from the foundation of the world,"[C] From that expression we see that Jesus was chosen to make the atonement from the foundation of the world, and that the gospel was understood from the beginning. The Prophet Joseph Smith said that "at the first organization in heaven we were all present, and saw the Savior chosen and appointed and the plan of salvation made, and we sanctioned it." [Footnote C: Rev. xiii: 8.]
