Bob Lupton, one of my heroes in urban ministry, posts a monthly reflection about life and faith in the city. It is called Urban Perspectives. 30 years ago, he moved into the inner-city of Atlanta as a response to God's call to live among and serve the urban poor and oppressed. These reflections are poignant vignettes of the life, love, difficulties, frustration, joy and all-around experiences of living in the city.
