North Korea’s first private university, PUST was founded and remains operated by actors outside the country, mostly Evangelical Christian organizations. While it is a secular school — North Korea keeps a tight grip on information about religion — the university chiefly employs Christian staff. The school has close historical ties to Yanbian University in Jilin, China, near the border with North Korea.
Despite poor conditions and the threat of imprisonment, the number of Christian believers in North Korea is growing, Kim said, and their faith is strengthened through persecution. “The one thing that the North Korean regime fears the most, and is afraid of, is the spreading of the Gospel,” he said. “Because the Bible and the Gospel speaks the truth.
"It may be difficult to imagine from the perspective of the 21st century, but the North Korean capital city of Pyongyang once had at its center a community of Americans—Christian missionaries who lived there from 1895 to 1942. ... The current capital was then the home of the largest Christian community in Korea and the center of the Presbyterian Church in Asia."
Christian Solidarity Worldwide report: "Among other basic human rights denied to the people of North Korea, freedom of religion or belief is largely non-existent. Denial of this right has occurred since the 1950s, and the current leader, Kim Jong-un, continues to violate citizens' religious freedom."
