In this class, we reach the introduction of evil into God's perfect creation. We learn of Satan's origin as a proud angel who rebelled and became the "father of lies," leading to the fall of humanity. We then examine the consequences of sin, including the curses placed on creation, mankind, and Satan, and, as a result, the separation from God. But God remains sovereign in the midst of the sin and evil, asserting His ultimate control and purpose in all things, even suffering. Understanding sin helps us better understand our need for daily repentance and engagement with scripture.
