Book excerpt: Global challenges fill the news today. It’s not always easy to balance fear with hope. That’s why this book points to resources for optimism and action. A diverse group of scholars draw on Jewish, Christian, Islamic, and Māori traditions to describe challenges and hopes. They recognize the ruptures of militarism, trauma, colonialism, religious nationalism, climate change, and more. But they also describe the healing power of communal action, spiritual practices, biblical literature, and the arts.
