John Hull is one of the UK's leading thinkers in Christian theological education and through his work over many years has shaped the discipline. His 1985 What Prevents Christian Adults from Learning? has become a classic. He has also been a pioneer in facilitating the connection between theological education, the life of the Church and prophetic action. This new book by John Hull, in many ways a sequel to What Prevents Christian Adults from Learning?, but much more than that, has been long awaited and draws together the different strands of Hull's work, who began life as a biblical scholar. He traces the tradition of the prophetic voice and prophetic action from the Old Testament to the present day and identifies it as a key resource for the renewal of the Church, not least through theological education. This book has the potential to become a classic of similar standing to his 1985 book. It will gain its place on reading lists on mission, ecclesiology and ministry as well as be of interest to all who regard social action as a key element of the life and work of the Church and seek to inspire others to do so.
