While the age of the Holy Spirit began with Pentecost, the twentieth century has seen an explosion in the Spirit's work through the remarkable growth of Pentecostalism and the changing face of global Christianity. Despite these surprising developments, and the undeniable significance of the Holy Spirit throughout the life of the church, pneumatology too often remains a subject of misunderstanding and neglect. These essays, gathered from the 2014 Wheaton Theology Conference, provide an ecumenical exploration of the Holy Spirit's person and work in biblical, historical, doctrinal and practical perspective. In addition to essays on Augustine, Aquinas, creation and salvation, the volume features important contributions on the current shape of global Pentecostalism by leading scholars in the field.
