After Satan and those who fell with him were shut out of heaven, and he realized that he had forever lost all its purity and glory, he repented, and wished to be reinstated in heaven. He was willing to take his proper place, or any position that might be assigned him. But no; heaven must not be placed in jeopardy. All heaven might be marred should he be taken back; for sin originated with him, and the seeds of rebellion were within him. Both he and his followers wept, and implored to be taken back into the favor of God. But their sin—their hatred, their envy and jealousy—had been so great that God could not blot it out. It must remain to receive its final punishment. (EW 146.1) MC VC

When Satan became fully conscious that there was no possibility of his being brought again into favor with God, his malice and hatred began to be manifest. He consulted with his angels, and a plan was laid to still work against God’s government. When Adam and Eve were placed in the beautiful garden, Satan was laying plans to destroy them. In no way could this happy couple be deprived of their happiness if they obeyed God. Satan could not exercise his power upon them unless they should first disobey God and forfeit His favor. Some plan must therefore be devised to lead them to disobedience that they might incur God’s frown and be brought under the more direct influence of Satan and his angels. It was decided that Satan should assume another form and manifest an interest for man. He must insinuate against God’s truthfulness and create doubt whether God did mean just what He said; next, he must excite their curiosity, and lead them to pry into the unsearchable plans of God—the very sin of which Satan had been guilty—and reason as to the cause of His restrictions in regard to the tree of knowledge.
