All heaven mourned on account of the disobedience and fall of Adam and Eve, which brought the wrath of God upon the whole human race. They were cut off from communing with God, and were plunged in hopeless misery. The law of God could not be changed to meet man's necessity, for in God's arrangement it was never to lose its force nor give up the smallest part of its claims. SR 46.2
The angels of God were commissioned to visit the fallen pair and inform them that although they could no longer retain possession of their holy estate, their Eden home, because of their transgression of the law of God, yet their case was not altogether hopeless. They were then informed that the Son of God, who had conversed with them in Eden, had been moved with pity as He viewed their hopeless condition, and had volunteered to take upon Himself the punishment due to them, and die for them that man might yet live, through faith in the atonement Christ proposed to make for him. Through Christ a door of hope was opened, that man, notwithstanding his great sin, should not be under the absolute control of Satan. Faith in the merits of the Son of God would so elevate man that he could resist the devices of Satan. Probation would be granted him in which, through a life of repentance and faith in the atonement of the Son of God, he might be redeemed from his transgression of the Father's law, and thus be elevated to a position where his efforts to keep His law could be accepted.

The angels related to them the grief that was felt in heaven as it was announced that they had transgressed the law of God, which had made it expedient for Christ to make the great sacrifice of His own precious life. SR 47.1
When Adam and Eve realized how exalted and sacred was the law of God, the transgression of which made so costly a sacrifice necessary to save them and their posterity from utter ruin, they pleaded to die themselves, or to let them and their posterity endure the penalty of their transgression, rather than that the beloved Son of God should make this great sacrifice. The anguish of Adam was increased. He saw that his sins were of so great magnitude as to involve fearful consequences. And must it be that heaven's honored Commander, who had walked with him and talked with him while in his holy innocence, whom angels honored and worshiped, must be brought down from his exalted position to die because of his transgression? SR 47.2
Adam was informed that an angel's life could not pay the debt. The law of Jehovah, the foundation of His government in heaven and upon earth, was as sacred as God Himself; and for this reason the life of an angel could not be accepted of God as a sacrifice for its transgression. His law is of more importance in His sight than the holy angels around His throne. The Father could not abolish or change one precept of His law to meet man in his fallen condition. But the Son of God, who had in unison with the Father created man, could make an atonement for man acceptable to God, by giving His life a sacrifice and bearing the wrath of His Father. Angels informed Adam that, as his transgression had brought death and wretchedness, life and immortality would be brought to light through the sacrifice of Jesus Christ. SR 48.1
