The person and work of the Holy Spirit is a neglected study in many churches. Some Christians think that the subject is so deep and mysterious that it is futile to study it. Others hesitate to emphasize the study of the Holy Spirit since some religious groups hold such extreme views regarding Him. Still, it is encouraging to see many Christians making a serious study of the Bible's teaching on the Holy Spirit. Dr. Jack Cottrell, with his "leave no stone unturned" approach to studying Scripture has completed the research for us tas he examines the many concepts and characteristics of the Holy Spirit. Power From On High: What the Bible Says About the Holy Spirit has 11 chapters and 503 pages. Jack Cottrell was long-time Professor of Theology at Cincinnati Christian University. He received his BA, ThB, Cincinnati Bible College and Seminary; BA, University of Cincinnati; MDiv, Westminster Theological Seminary; PhD, Princeton Theological Seminary.
