This book is especially written for young people who want to understand more about what service means in Christian perspective. It is addressed to people whose experience in service has led them to want to think more clearly and deliberately about its meaning and significance, especially in religious terms. It presumes a genuine interest in–but not necessarily a strong commitment to–Christianity. It regards Christianity neither as a moral code nor theory of the world nor religious special-interest group, but as a way of life that centers on Jesus Christ. Christians are known for following a Master who taught us to regard our lives as called to loving service of one another and the wider world. Yet we find it difficult to talk about the connection between Christian faith and service, or at least to talk about it in nuanced and complex ways. This book has been written to help overcome the gap between our language and our experience.
