How does Christ call his people to engage the societies, cultures, and politics of the nations they call home? From prioritizing patriotism over faith to withdrawing from the public sphere entirely, the struggle to navigate the intersection of an earthly and heavenly kingdom remains an ongoing challenge for Christians around the world. Bridging cultures and time periods, Dr. Surya Harefa brings Abraham's Kuyper's ecclesiology to bear on questions of Japanese Christian engagement within the political sphere. Harefa offers a contextually robust exploration of evangelical Japanese approaches to ecclesiology and political involvement. Taking care to place Kuyper's conception of the church within Kuyper's own political and historical context, careful lines of application are drawn between Kuyper's theological perspectives and the need for an active Japanese church engaged in all spheres of life. This book is an excellent resource for those seeking to equip Christians to engage politically as followers of Christ for the good of the church and their nations. It also provides an example of the rich and powerful insight offered by exploring Western and non-Western theologies within their diverse contexts and in conversation with each other.
