This lesson discusses the origin and development of the war between good and evil. It will cover the consequences of Satan's rebellion against God and how God counteracted it through the plan of salvation. The lesson traces Satan's rebellion from his original position as Lucifer, the most beautiful of God's creatures, to his desire for power and position over God. This resulted in a war in heaven where Satan and his angels were defeated and cast out. Satan then deceived Adam and Eve and brought the war to Earth. God's plan of salvation through Jesus' life, death and resurrection defeated Satan and provides victory over sin and death for humanity.
