Those that have to do with business and work; Those that have to do with submission and respect for authority; Those that have to do with personal responsibility before God. Those principles that tell him how to work also tell him to do so “heartily.” They tell him to work, not in order to please people, but in order to please Christ (Col. 3:22-25; Eph. 6:5-8). That means that he must be concerned about doing the best job that he can for his employer—for Christ’s sake.
