Humans are often ignorant or indifferent about the role of sin and Satan in our lives. In Sin: Satan's Playground, author Kelly Bauserman discusses the reality of sin and how it affects all of our lives when we are not diligent in warding off this enemy. Using quotes and excerpts from the Bible, Sin presents a detailed explanation of Satan's temptations, including materialism, the lust for power and money, and fornication. It relays the importance of knowing this enemy and how to defeat him in our daily lives. It also describes the armor of God and gives personal examples of Bauserman's battle with his enemy, the devil. Through a vivid discussion of the power of the Lord Jesus over Satan, Sin invites Christians to accept Jesus into their lives, live a clean life, avoid temptation, and wear the armor of God in order to ward off the devil.
