Satan watched every event in regard to the sacrificial offerings with intense interest. The devotion and solemnity connected with the shedding of the blood of the victim caused him great uneasiness. To him, this ceremony was clothed with mystery; but he was not a dull scholar, and he soon learned that the sacrificial offerings typified some future atonement for man. He saw that these offerings signified repentance for sin. This did not agree with his purposes, and he at once commenced to work upon the heart of Cain, to lead him to rebellion against the sacrificial offering which prefigured a Redeemer to come. (Con 22.1) MC VC

Adam’s repentance, evidenced by his sorrow for his transgression and his hope of salvation through Christ, shown by his works in the sacrifices offered, were a disappointment to Satan. He hoped forever to gain Adam to unite with him in murmuring against God and in rebelling against His authority. Cain and Abel were representatives of the two great classes. Abel, as priest, in solemn faith offered his sacrifice. Cain was willing to offer the fruit of his ground, but refused to connect with his offering the blood of beasts. His heart refused to show his repentance for sin, and his faith in a Saviour, by offering the blood of beasts. He refused to acknowledge his need of a Redeemer. This, to his proud heart, was dependence and humiliation. (Con 22.2) MC VC
