I wonder if people aren't a little suspicious when we preach about work. When we say that all work is a calling, and that all work is good and important, I wonder if some have trouble swallowing it. Consider the guy who gets depressed every Sunday night at the prospect of going back to the office or the woman who faces incessant complaints and impossible demands. I think some people gratefully accept their jobs as God's call, but for others it is a hard sell. It can be very hard to think Christian-ly about jobs.
While preaching through the Book of Ephesians, I came to the subject of work. I like preaching through a book of the Bible because, for one thing, the Scriptures set my preaching agenda. I didn't actually decide to preach on work (or the nature of the church or marriage). The Holy Spirit used Ephesians to decide for me. I also like staying put in that one passage, rather than trying to do a broad topical sermon on a subject like work. That means that I don't cover all the Bible has to say about work, but it also means I am forced to look deeply into the thoughts of this one passage.
