Despite the perception of North Korea as a country hermetically sealed to the outside — and despite the very real risks — dozens, if not hundreds, of Christian missionaries operate inside the country, sometimes living there for months at a stretch, in the capital, Pyongyang, or in the Rason region, near the country’s Chinese border. Some run factories, distributing bread and soy milk to the poor. Others work for NGOs or universities, like the Pyongyang University of Science and Technology, North Korea’s first privately funded university (launched in 2010), which is bankrolled mostly by evangelical Christian movements. Its founder James Kim, who has spent prison time in North Korea for proselytizing, likes to say that he has “unlimited credit at the bank of heaven.”
