Satan’s Guilt Was So Great It Was Unpardonable

The divine Son of God saw that no arm but his own could save fallen man. He determined to help man. He left the fallen angels to perish in their rebellion, but stretched forth his hand to rescue perishing man. The angels who were rebellious were dealt with according to the light and experience they had abundantly enjoyed in Heaven. Satan, the chief of the fallen angels, once had an exalted position in Heaven. He was next in honor to Christ. The knowledge which he, as well as the angels who fell with him, had of the character of God, of his goodness, his mercy, wisdom, and excellent glory, made their guilt unpardonable. — {RH February 24, 1874, par. 33}

The Saviour of the world had no controversy with Satan, who was expelled from heaven because he was no longer worthy of a place there. He who could influence the angels of God against their Supreme Ruler, and against his Son, their loved commander, and enlist their sympathy for himself, was capable of any deception. — {1SM 279; RH, August 18, 1874}

Satan acquired the supremacy as a legislator in guilt to compel by decree the transgression of God’s law, and the professed Christian world come under his banner fully choosing his service and shall do after the works of the fallen foe. The rebellious chieftain signalized himself as having authority to establish laws entirely contrary to the laws of Jehovah, the living and only true God, the supreme Ruler in heaven and in earth. — {8LtMs, Lt 60, 1893, par. 8}

When Satan became fully conscious that there was no possibility of his being brought again into favor with God, then 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. A consultation was held with his evil angels. 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. They must devise some plan 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, create doubt whether God did mean as he said, next, excite their curiosity, and lead them to pry into the unsearchable plans of God, which Satan had been guilty of, and reason as to the cause of his restrictions in regard to the tree of knowledge. — {1SG 19.1}

After Satan was shut out of heaven, with those who fell with him, he realized that he had lost all the purity and glory of heaven forever. Then he repented and wished to be reinstated again in heaven. He was willing to take his proper place, or any place 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. Satan had obtained followers, those who sympathized with him in his rebellion. He and his followers repented, wept and implored to be taken back into the favor of God. But no, their sin, their hate, their envy and jealousy, had been so great that God could not blot it out. It must remain to receive its final punishment. — {1SG 18.1}

Satan, who first tempted Eve in Eden, and through her caused the fall of Adam, continues his temptations, seeking by every power to retain men in disobedience. Every lying device is put into operation to misrepresent the Father and to dispute the authority of his only-begotten Son. Satan casts a hellish shadow before the world to hide God and the world's Redeemer from sight, so that if they were viewed at all, it might be through the mists and fogs of superstition, tradition, and error, and not in truth. — {ST March 28, 1895, par. 6}

Satan seeks to keep himself and his work in disguise. He does not wish to be known as the one who in heaven sought to be equal with God and brought on a war amongst the angels.  — {18LtMs, Ms 102, 1903, par. 14}
