This work is another edition of the "NAC Studies in the Bible & Theology" series. This book is a careful study and biblical investigation into the role and work of the Holy Spirit in the times of the Old Testament and the New Testament in the lives of those who were believers. Considered are the differences before and after Pentecost as well as under the covenants of Scritpure. It is helpful in bringing out the relevant Scriptures that give some revelation as to how God the Spirit is involved in His creation, man in particular.
