Would you like to work at one of the biggest universities in the United States? Come to work as a campus missionary with Christian Challenge (BCM) at the University of Arizona. We have 53,000 students on campus, with less than five percent of them being Christian. If you want to come work in the West and enjoy the challenges of working in an unreached area of the United States, this would be the place for you. We do raise our own support for our salary.
