In Every Good Endeavor, Tim Keller helpfully reminds his readers that having a secular job doesn’t get us off the hook of being “used by God”:
Dick Lucas, an English Anglican preacher, once preached a sermon on the story of Joseph. […] He said that if you were to go to a book table at a church and see a biography with the title The Man God Uses or The Woman God Uses, you would immediately think it was the story of a missionary, teacher, church leader, or specialist in some sort of spiritual work. He points out that what you have in the story of Joseph is a highly successful secular official. Lucas says, “In the long term I think being a preacher, missionary, or leading a Bible study group in many ways is easier. There is a certain spiritual glamour in doing it, and what we should be doing each day is easier to discern more black and white, not so gray. It is often hard to get Christians to see that God is willing not just to use men and women in ministry, but in law, in medicine, in business, in the arts. This is the great shortfall today.
This reminder from the account of Joseph is both chastening and encouraging. It is encouraging for Christians who work in “secular” professions and want to make the most of their lives for God. It is chastening for Christians who think they can crank out their “secular” work no differently to anyone else and just worry about being a Christian on the weekends.
