Though countless Christians through the ages have confessed, "I believe in the Holy Spirit," the Spirit has often remained a shadowy figure, relegated to the fringes of many Christians' faith. In some quarters, however, the rise of the charismatic movement has made the Holy Spirit a focus of heated controversy. In this updated edition of his widely popular book, Michael Green traces the doctrine of the Holy Spirit through the Bible, discusses the baptism and gifts of the Spirit, and addresses the dynamic, ongoing work of the Spirit in today's church and world. Enriched by Green's extensive teaching, pastoral, and personal experience, I Believe in the Holy Spirit remains one of the clearest, most balanced books ever written on this subject.
