Language about the Holy Spirit in church worship is confused and contradictory. This can lead to extremes in which the Spirit may appear limited to the ministry of bishops and elders, or is believed to be manifest in signs and wonders which alone are held to be the marks of the true church. This book is written for congregations, clergy and leaders by a leading international authority on the Old Testament(a non-charismatic Christian). He helps readers navigate and understand the church's perplexing language about the Holy Spirit, using insights from scholarship and his long experience of working as a priest. Based on sermons from his regular ministry, each chapter carefully explores and illuminates biblical references to the Holy Spirit, encouraging readers to believe that God is on the inside of his creation, in the world and the church, even when 'results' are not spectacular in a human sense. Where the Gospel is faithfully preached and heard, the Spirit of God is at work.
