If you're a Christian, you may be familiar with the notion that some work is more holy (such as being a missionary or a pastor), while other work (being a doctor, businessperson or a carpenter, for example) is less so. This faulty understanding of work leaves God out of the big picture of our everyday work. R. Paul Stevens discusses in this video. 

"When I hear somebody say 'I'm going into full time ministry'...I want to throw up...because it communicates that there's a part-time option, and there isn't." - R. Paul Stevens, Professor Emeritus of Marketplace Theology and Leadership at Fuller Theological Seminary
