Davis presents the case that one key aspect of being an overcomer for the Christ follower is the notion of spiritual authority. Living in a world that is rooted in power, Christ followers are challenged daily by powers that seek to interrupt or trample their success in the journey through Christ--the world and the kingdom of darkness. Davis believes that while followers receive empowerment from the Holy Spirit, this power is only fully operational as they function out of their God-given authority. As believers, everything they need is at their disposal. However, they must actively appropriate their authority, both in attitude and in action. Davis provides a biblical theology of authority and real life examples of how he and others have embraced their spiritual authority to advance the kingdom of God. In essence, it is a manual for overcoming spiritual opposition in everyday life.
