In the contemporary church, the word 'mission' has become synonymous with pace, expansion and results. Yet such an approach can often leave those with responsibilities in mission or ministry feeling exhausted and overwhelmed. Not only that, but mission which focuses on the rapid and the growing fails to recognise the rich resources the more contemplative Christian traditions can offer our post-secular society, and especially those who would call themselves 'spiritual but not religious'. In 'The Seeking Heart', Ian Mobsby calls for an approach to mission which takes a deeper, slower spirituality more seriously. Drawing on the work of a wide range of figures within the Christian tradition, from John of the Cross and Hildegard of Bingham to John Taylor, he boldly calls the church to a new kind of mission which takes spirituality more seriously, and offers a model to demonstrate what such an approach might look like in practice.
