2 Thessalonians 3:6-18
V. 13: Brothers and sisters, do not be weary in doing what is right.
In this case, Paul was talking about his instructions for the Thessalonians in regard to work and idleness. Many of the Thessalonians had apparently come to believe that either the Lord had already come or his coming was in process. So why work? Paul is quite harsh with them: "Anyone unwilling to work should not eat."
It has always been interesting to me that we don't have much of a theology of work. Somehow, for many if not most of us, our vocational life has become about us, not about God. This can even happen to clergy. I can't expound a theology of work here, but I can say that I think it has to do with participating in God's ongoing creation--being a continual co-creator with God. It also has something to do with the relationship of the individual to the community where some important balances have to be maintained. And it also has to do with "not growing weary of doing right."
How is your work a work for God? I suspect that's a daunting question for some of you, but remember "work for God" does not mean "work for the church." It means "work for the creation."
