What is the meaning of the Holy Spirit's activity in Luke-Acts, and what are its implications for today? Roger Stronstad offers a cogent and thought-provoking study of Luke as a charismatic theologian whose understanding of the Spirit was shaped wholly by his understanding of Jesus and the nature of the early church. Stronstad locates Luke's pneumatology in the historical background of Judaism and views Luke as an independent theologian who makes a unique contribution to the pneumatology of the New Testament. This work challenges traditional Protestants to reexamine the impact of Pentecost and explores the Spirit's role in equipping God's people for the unfinished task of mission. The second edition has been revised and updated throughout and includes a new foreword by Mark Allan Powell.
