Martin Luther on vocation

The idea that the service to God should have only to do with a church altar, singing, reading, sacrifice, and the like is without doubt but the worst trick of the devil. How could the devil have led us more effectively astray than by the narrow conception that service to God takes place only in a church and by the works done therein? The whole world could abound with the services to the Lord, Gottesdienste - not only in churches but also in the home, kitchen, workshop, field.
