Some people believe that there is a difference (albeit inconsiderable) between a Christian and a believer. They argue that a Christian has not completely understood the valid, valuable, and invaluable role that the Holy Spirit plays in serving Christ. They aver that a believer, on the other hand, is a Christian who has learned and developed a conviction born from experience that, without a daily contact and yielding to the Holy Spirit, could not be true to God, let alone communicate with Him. The question is, are you willing, hungry, and determined to communicate with God on behalf of lost souls in ways that would enrich your participation and discipline your understanding about the great commission as a prayer warrior? Prayer warriors are believers who have made a conscious effort to intercede for lost souls and to reach the world for Christ. They believe and have this inveterate conviction that prayer undergirds witnessing, and witnessing cultivates a culture of absolute and undeviating dependence on the Holy Spirit. They also believe that the church exists to witness for Christ. This book is about the Holy Spirit and His influence on all aspects of prayer. That is why any church qua church that does not have a group of dedicated men and women whose avowed mission is to pray for souls (prayer warriors) is making itself irrelevant in preparing for the second return of Christ. As you read, whether it is the chapter on prayer and the knowledge of God, prayer and the will of God, prayer and praise, prayer and faith, prayer and witnessing, prayer and the sovereignty of God, or secret prayer, you will discover, as I did, that the Holy Spirit stands ready to transform your own life because "He that watereth shall himself be watered" is an inflexible Biblical principle. My hope is that the Holy Spirit will not only fight for His outcomes as you read and apply these principles in your own life but also leaven your conviction.
