Business as mission experience growth following a mission movement in the 1980's to reach people in what was referred to as the "resistant belt" across North Africa, the Middle East and Asia.  

These locations were typically Muslim, Buddhist or were simply ruled by governments that made it hard or impossible for religious workers to get visas.  Missionaries with no business experience opened travel agencies, Internet cafes and other small companies, sometimes accused of being little more than fronts for proselytizing.

According to Steven L. Rundle, an associate professor of economics at Biola University in La Mirada, Calif., that model was about getting missionaries into these countries by whatever means you could, whether it's teaching or business or whatever.  
Professor Rundle authored a 2003 book, "Great Commission Companies: The Emerging Role of Business in Missions."

Since that time there have  been evangelical groups recognizing that mission-minded businesspeople can do things that traditional missionaries cannot.   Rundle stated, "The future generation of missionary will be the rank-and-file businessman,"  
The wheel, he added, has come full circle: many of the first emissaries of the Gospel were tradesmen, not priests.

Next time we will see some example work in Romania.
