“Do Christians in today’s working world ever find themselves confronted by issues not directly addressed in the Bible?”
This may sound off-topic, but work with me here. I have never been a fan of applying the slave/master verses of the New Testament to modern employment arrangements. The two situations are simply not analogous. I have known people who felt trapped in dead-end jobs, but even in the worst modern employment situations, the employee is legally free to take his leave any time he chooses on a mere two weeks notice. It’s not the law of the land or the middle manager he reports to that make him feel trapped, but rather his personal financial situation.
That’s not to say there is nothing in the New Testament to address the issues faced by Christians in today’s working world, but let’s be careful what we do with those slave and master passages.
