Vital Teaching on an imperative, timeless topic from Derek Prince, now updated and expanded with several brand-new chapters and reflection questions following every chapter, this landmark text offers the most important and practical guidance Derek Prince imparted to believers in his last years: how to prepare for and take their places in the ultimate, ongoing spiritual battle. With superb biblical exposition and hands-on application, Prince explains that Christians need to be more than just disciples, they need to be warriors. He shows them how to build a warrior's character, to face testing, to fight alongside the Holy Spirit, to influence the outcomes of spiritual battles, and more. With this manual in hand, believers will learn how to fulfill their roles confidently in both day-to-day trials and in God's plan for the finale of the ages.
