Night and day I pondered until I saw the connection between the justice of God and the statement that 'the just shall live by his faith.' Then I grasped that the justice of God is that righteousness by which through grace and sheer mercy God justifies us through faith. Thereupon I felt myself to be reborn and to have gone through open doors into paradise.
Martin LutherThe devil, the originator of sorrowful anxieties and restless troubles, flees before the sound of music almost as much as before the Word of God....Music is a gift and grace of God, not an invention of men. Thus it drives out the devil and makes people cheerful. Then one forgets all wrath, impurity, and other devices.
Martin Luther
