How are we to sustain activism and compassion amidst the never-ending crises of the twenty-first century? While the concern for social justice is deeply biblical, cynicism, burnout, and despair are all too common side effects when action is divorced from contemplation. To effectively serve as the hands and feet of Jesus, the church must attend to the revitalization of its inner life through the spiritual practices which feed, support, and sustain the work of the kingdom. Rather than the fragmentation and dualism that have led denominations to choose between prayer and service, evangelization and justice, the church must integrate heart, mind, and body in order to fulfil its calling to transform the world from within. Drawing from Scripture and a wide range of Christian traditions - from the monastic to the evangelical - this book inspires its readers to integrate spiritual renewal and prophetic witness for the glory of God and the good of his creation.
