Ross has provided a critical and constructive account of faith through the lens of pneumatology. Engaging with Paul Tillich, the New Perspective on Paul and the theology of faith, it takes the conversation in a different, holistic, and participatory direction using Pentecostal dialogue partners. This is a book that should be read by biblical and systematic theologians, especially those who are sympathetic to Pentecostal and Charismatic theology. However, given its engagement with a range of interdisciplinary and ecumenical sources, there is much that contributes to the wider theological academy. I would encourage students and scholars to read this book. It may change your understanding of the concept of faith in relation to the Christian life!
