~ The Cost of Discipleship compels the reader to face himself and God in any situation. Bonhoeffer speaks of "Cheap Grace": preaching forgiveness without requiring repentance, baptism without church discipline, communion without confession. "Cheap Grace" is grace without discipleship. "Costly Grace" is the gospel which must be sought again and again, the gift which must be asked for, the door at which a man must knock. "It's costly because it costs a man his life, and it is grace because it gives a man the only true life."
