A new generation of Christians believes God calls them to seek shalom in their cities. These Christians are using their gifts and energies in all sectors of public life—commerce, government, technology, the arts, media, and education—to bring systemic renewal to the cultural "upstream" and to bless their neighbors in the process. No longer on the sidelines of influence, emboldened by the belief that Jesus loves cities, they model a distinctly evangelical civic engagement for the 21st century. This Is Our City, a multiyear project of Christianity Today, seeks to spotlight in reporting, essays, and documentary video how these Christians are responding to their cities' particular challenges with excellence, biblical faith, and hope. The six cities we are profiling differ dramatically from one another in size, economic climate, ethnic and racial composition, and in their history of Christian presence, leadership or abdication, at crucial moments. But they all have stories worth telling. Wherever we live, we can learn something from these cities about faithfulness to our own place.
