From Faith and Action (1938) by Helmut Stellrecht for the Hitler Youth:
You should never do anything for pay, but rather always because it is worth it for its own sake. Did ever a German soldier go to war for the sake of money? He did it for the Fatherland. He who asks us to be good and pious for money seduces us and draws us away from god. He is the devil’s advocate, even if he promises us heaven.
§ God is in the good that we do, but he is not in a heaven that we will enjoy for eternity.
§ It is German to do something for its own sake. Such was always the first and highest service to god in Germany, and thus it will remain as long as our nation lives and the world is there to warn us.
