I recently heard about someone who said he was the pastor of Taco Bell. It sounded corny at first. The person explained that he had intended to graduate from college and to go for pastor training but that plan didn't materialize. So in his 'interim' part-time work, he was going to look for ministry opportunities in his everyday Taco Bell work. That person felt called and was willing to do kingdom work in everyday life just as all Christians should do.
