This thesis works toward a constructive Pentecostal theology of the Spirit in the Former Prophets. Chapter one provides a history of interpretation (from 1896 to present) of major works engaging the Former Prophets with regard to the Spirit. Chapter two offers a Pentecostal hermeneutic of the Former Prophets. Chapter three provides a history of effects (or Wirkungsgeschichte) approach by hearing the Spirit texts of the Former Prophets alongside of early North American Pentecostals (specifically the journals from 1906-1920) in order to offer a better orientation to how Pentecostal communities have interpreted these texts in their formative years. Chapters four through seven apply the hermeneutic of chapter two to the groupings of texts of the Spirit in the Former Prophets. As such, the chapters that follow are larger literary units which include multiple references to the Spirit of Yahweh/God, but are grouped together as narratological units. Chapter four addresses the judges who explicitly experience the liberating Spirit of Yahweh. Chapter five addresses Saul and David’s musical and prophetic experiences of the Spirit of Yahweh/God both for good and ill. Chapter six addresses the ambiguities of the Spirit in the context of the prophet Micaiah. Chapter seven addresses the passing of the Spirit of true prophetic sonship from Elijah to Elisha. Chapter eight then attempts a constructive Pentecostal theology of the Spirit in light of the study of the Spirit in the Former Prophets laid out in the preceding exegetical chapters and the Wirkungsgeschichte of chapter three. Finally, the concluding chapter briefly summarizes the contributions of this study and entertains multiple potential directions for future study brought to light through this study.
