Grace

"Cheap grace is the grace we bestow on ourselves... the preaching of 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 sough again and again, the gift which must be asked for, the door at which a man must knock...

It is costly because it costs a man his life, and it is grace because it gives a man the only true life." 

 Dietrich Bonhoeffer {The Cost of Discipleship}
