Today, Iowa Public Radio concludes its five-part series on African-Americans in the state. Reporter Rob Dillard has looked into the issues they face in the areas of education, employment, politics and health. He ends with a story about faith. The church has historically played a crucial role in the lives of many African-Americans. It has been in the pews of black churches where they’ve found comfort and inspiration. Rob takes us to a Sunday-morning service in Waterloo where parishioners are charting their paths toward spirituality.
