Bloodlines (2011)

This is a well-done 18-minute documentary with John Piper revisiting his roots in Greenville, South Carolina and recounting how the gospel delivered him from the racist attitudes of his youth. The main thing I took away from this is that it's possible to grow up in a Christian home as a saved individual and still be in the grip of deep generational and societal sin. Thank God for the gospel of Jesus Christ that turns racists into agents of reconciliation!
