'Happy are they who have reached the end of the road we seek to tread, who are astonished to discover the by no means self-evident truth that grace is costly just because it is the grace of God in Jesus Christ. Happy are the simple followers of Jesus Christ who have been overcome by his grace, and are able to sing the praises of the all-sufficient grace of Christ with humbleness of heart. Happy are they who, knowing that grace, can live in the world without being of it, who, by following Jesus Christ, are so assured of their heavenly citizenship that they are truly free to live their lives in this world. Happy are they who know that discipleship simply means the life which springs from grace, and that grace simply means discipleship. Happy are they who have become Christians in this sense of the word. For them the word of grace has proved a fount of mercy.'
Dietrich Bonhoeffer, The Cost of Discipleship, p.14.
