Reparations for African Americans

The U.S. government actually began the process of reparations with african americans during the civil war. This was a stunning act, way ahead of its time. Sadly, not long after this order, president andrew johnson, lincoln's successor, overturned the order and returned the land back to its original treasonous owners. So how are we as christians to respond to this? What does it mean to think and behave christianly when it comes to reparations?
