The call to the cloister demanded of Luther the complete surrender of his life. But God shattered all his hopes. He showed him through the Scriptures… - Dietrich Bonhoeffer

God did not reckon his Son too dear a price to pay for our life, but delivered him up for us. Costly grace is the Incarnation of God. Costly grace is the sanctuary of God; it has to be protected from the world, and not thrown to the dogs. It is therefore the living word, the Word of God, which he speaks as it pleases him. Grace is costly because it compels a man to submit to the yoke of Christ and follow him; it is grace because Jesus says: "My yoke is easy and my burden is light."

Nicht aus dem schweren Boden
wo Blut und Geschlecht und Schwur
mächtig und heilig sind,
wo die Erde selbst
gegen Wahnsinn und
die geweihten heilgen uralten Ordnungen
hütet und schützt und rächt, —
nicht aus dem schweren Boden der Erde,
sondern aus freiem Gefallen
und freiem Verlangen des Geistes,
der nicht des Eides und des Gesetzes bedarf,
wird der Freund dem Freunde geschenkt.

Man seeks, in his manhood, not orders, not laws and peremptory dogmas, but counsel from one who is earnest in goodness and faithful in friendship, making man free.
