More people live in cities now than at any other time in human history, presenting a historic opportunity for Christians to influence the majority of the world. Unfortunately, most Christian literature about the city focuses solely on its problems (crime, homelessness, etc.), rather than providing a comprehensive analysis of the city that informs, instructs, and inspires. Using sociological research and data, urban pastors Justin Buzzard and Stephen Um lay out the vision and rationale for church planting, cultural engagement, and missionary impulses in our world's cities as they provide a solid foundation for motivation. Here is a call to make the cities our home, to take good care of them, and to participate in God's kingdom-building work in the urban centers of our world!
