In "God's Word for Today" Gordon Snider writes:
Among the many things that have changed in my life-time is the employment picture in the USA. It used to be that a person spent an entire working career with one employer. The employee felt a certain amount of loyalty to the employer, and the employer felt a certain amount of responsibility for the needs of the employee, either because the employer had a generous heart, or because he was under contractual constraints with a union. Today, long-term commitment in the marketplace seems largely a thing of the past. And the resulting “dog eat dog” atmosphere makes it even more difficult for the employee to work “as unto the Lord.” It is important to remember that the biblical principles concerning master/servant weren't written under ideal conditions either. By almost any standards slavery is far worse than today's selfish employment theater, but whatever the social conditions of the day, the principles of God's Word remain the same. Be careful! Thoughtful attention to today's lesson may require an attitude change when you head to work tomorrow!
