Imagining the Future: The Origin, Development and Future of Assemblies of God Eschatology (Tulsa: ORU Press, 2021).
Since the Assemblies of God began in 1914, a great importance was placed on the belief in the second coming of Christ. However, in recent decades, a segment of AG ministers and educators have begun to re-examine the theological underpinnings of the denomination’s eschatology. Many of the historic expressions of eschatology are losing popularity within Pentecostal circles, particularly the long relationship with dispensational premillennialism.
Through doctrinal criticism, this book provides comprehensive analysis of AG eschatological positions over the past century from three distinct voices within the AG community. First, it surveys the field of attitudes about AG eschatological positions within the field of Pentecostal academics by leading AG scholars. Second, it offers a historical analysis of the development of official AG statements on eschatology found in the statements of faith and approved position papers. Third, it provides a reception history of how eschatological doctrines were received and expressed by AG adherents in the Pentecostal Evangel, the official organ of the AG, from 1914–2005. In each of these voices, particular attention is given to how these expressions were shaped by the pneumatological beliefs, historical events, and the influence of dispensationalism.
The work concludes by drawing from the pneumatological imagination to imagine the future of AG eschatology by integrating the various historical expressions of AG eschatology into a contemporary, yet contextual, set of eschatological doctrinal expressions to solidify the importance of the second coming of Christ for a new generation of Pentecostal believers.
Pentecost in Tulsa: The Revivals and Race Massacre that Shaped the Pentecostal Movement (Lanham, MD: Seymour Press 2020).
Pentecost in Tulsa tells the story of how Tulsa became an important epicenter of Pentecostal and Charismatic Christianity in the United States. In its earliest days, revivals helped establish important Pentecostal churches. Later, well-known evangelists in the movement, launched worldwide ministries from Tulsa that impacted millions around the globe. This book also reveals the untold story of a resilient black Pentecostal community that endured the 1921 Tulsa Race Massacre and succeeded in reviving the famous Greenwood District. Through these triumphs and tragedies, Tulsa has emerged as a significant city with continuing impact on the Pentecostal movement

Pilgrimage Into Pentecost: The Pneumatological Legacy of Howard M. Ervin: Word & Spirit Press, 2008
Pilgrimage into Pentecost explores the life and legacy of Howard M. Ervin,Th.D., chronicling Ervin’s pilgrimage from his beginnings as Baptist pastor to his global influence as a Pentecostal leader. His exegetical theology led him to advocate a distinctively Lukan theology of the Holy Spirit, and he became for a while the leading scholarly apologist for the classical Pentecostal doctrine of Spirit baptism. Ervin’s scholarship spurred fruitful theological debate on the contemporary work of the Holy Spirit, especially with New Testament scholar James D.G. Dunn, while his extensive ecumenical pastoral ministry demonstrated the Spirit’s work of unifying the body of Christ. Pilgrimage into Pentecost not only pays well-deserved tribute to a pioneer of Pentecostal scholarship but also offers his devout scholarship and distinguished forty-year teaching career at Oral Roberts University (ORU) as an example for others.
