WHAT MADE SATAN FEEL UNEASY?

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 }
