Passion, Power, and Promise is an engaging study of the Holy Spirit from a global perspective. Robert Fennell invites the reader into a journey of discovery about the distinctive identity and activity of God the Spirit, who longs for the transformation of all people and the whole creation. Special attention is given to the ancient sources of the Christian faith, the Reformers, and the contributions of the world's United and Uniting Churches. Questions for reflection are included with each chapter, suitable for individual and group use.
