Book Summary Jerry Rankin’s book, In Spiritual Warfare: The Battle for God’s Glory, has ten chapters. The author discusses a wide range of topics that concern spiritual warfare. Rankin begins chapter one by giving examples of the realities of spiritual warfare by narrating his encounters as a missioner in the mission field. The author begins by challenging the readers to acknowledge that demonic possession goes beyond the physical body. Spiritual warfare is always a well-orchestrated battle that is disguised as a physical possession. According to Rankin, Christians fail to discern spiritual warfare sometimes because they have brushed it off as a myth. The author states that before going into missions, his spiritual sensitivity like that of many other Christians was low. However, after being in the field for a while and interacting with people who did not know Jesus, his spiritual sensitivity increased. He states that every Christian must know that demonic possession is very common in places where the gospel is yet to be preached. In this chapter, Rankin urges Christians to work on their spiritual sensitivity. Spiritual warfare goes beyond the primary focus, viz. Satan. Rankin argues that spiritual warfare has three dimensions, viz. Satan, the world, and the flesh. These three are always conspiring daily to defeat Christians and they work closely to ensure that they rob God of His glory. A proper understanding of who God is in the lives of Christians is important if they are to understand the spiritual warfare and its proponents. Rankin states that the distorted perception of God, Satan, and spiritual warfare convinces people that Satan has power over them. However, in reality, he does not have such power, and thus Christians end up giving in to fleshly desires without resistance. In the next three chapters, the author capitalizes on the nature of the devil. He begins by noting that the term ‘devil’ in Greek is Diabolos, which means to oppose. Rankin notes that the ultimate goal of God is for Christians to glorify Him and ensure the growth of His kingdom. The devil comes in at this point with a completely new strategy in opposition to the goal of God. The strategy is to convince that doing missions is an option. According to Rankin, Jesus tasked His disciples to traverse all nations making disciples, and thus Christians should understand that missions are not an option. Rankin states that what makes it easier for the devil to convince Christians is the fact that his lies and oppressions are not blatant, but disguised. According to Rankin, Satan has blinded those who do not believe in the gospel so that they are unable to understand it. He affirms this assertion by stating that in his various missions, he has interacted with people who react to the gospel with such fierce hostility. Rankin notes that it is very important for Christians to abide in fellowship with God. Apparently, the devil does not get opposition when manipulating believers because they do not know the truth. He emphasizes that if Christians had a healthy relationship with God, it would not be easy for Satan to manipulate them. The author goes ahead to note that the Bible reveals three categories of temptations, which include “lust of the flesh, the lust of the eyes, and pride in one’s lifestyle” (Rankin 2009, 301). Satan uses these tools to manipulate Christians. Rankin also looks at the struggles that Christians face in their walk of
