Although the Holy Spirit is present and busy in the whole Bible, most times He is relegated to the New Testament and more specifically, to the book of Acts after the Day of Pentecost. What was the Holy Spirit's role in the Old Testament? How is He recognized in the life of a believer? Is His presence in a believer the same as His presence upon a believer? Is "speaking in tongues" really necessary? What is the use of speaking to God in a language that we do not understand if we can speak to Him in a language that we understand? How does "speaking in tongues" benefit the people around me? This is a book on spiritual warfare and as such it emphasizes the role of the Holy Spirit in this warfare, both in the Old Testament and in the New Testament. The best person to introduce the Holy Spirit is the Holy Spirit Himself My prayer is that as you read this book, the Holy Spirit will reveal Himself to you in a way that has never happened before. He is wonderful He is awesome Without Him we cannot know Jesus or God the Father. He has been give full jurisdiction to move in and upon people on earth, to fulfil the will of the Father.
