A focus on physical fitness is part of modern culture, at least for some, with the number of gyms and memberships at an all-time high. Not so when it comes to spiritual fitness. Graham Tomlin argues that much of the modern church is spiritually flabby, its members lacking distinctiveness as Christians and its impact on modern culture correspondingly limited. What can be done? Physical health and fitness require discipline, self-denial and cost; so, too, with spiritual fitness. This is a very practical book giving churches and their members tools with which to start to reverse the trend of spiritual blandness, and to feel more confident as Christians in the modern world. Not only will this benefit those concerned but there will be a new impact on society as the church becomes more appealing, relevant and significant. This book is for all who feel dissatisfied with their Christian faith, who are concerned about the future of the church, or who want to see the church being much more relevant to modern culture.
