The idea of worship in work was at once a doctrine and a daily discipline. The ideal was variously expressed that secular achievements should be as "free from error" as conduct, that manual labor was a type of religious ritual, that godliness should illuminate life at every point.
It really boils down to this: that all life is interrelated. We are all caught in an inescapable network of mutuality, tied to a single garment of destiny. Whatever affects one directly, affects all indirectly.
