Presently, there are more than 27,000 North Korean defectors living in South Korea, and many are practicing Christians who regularly attend church.

Yosep (Joseph) Cho is a senior pastor and former professor at the Police Academy in Seoul teaching about North Korean refugees adapting to South Korea. He has been working with North Korean defectors for more than 20 years and his church, Muldaedongsan Church in Seoul, provides resettlement services as well as  church services to North Korean defectors in South Korea. In 2014, he published his book Talbukja: Bukhanseongyouimajungmul (North Korean Defectors: The Well Pumping Water of North Korean Missionary Work) published by Dunalgae (Two Wings Publishing), in which he argues that current North Korean defectors in South Korea, particularly those of a younger generation, are the key to bridging the two Koreas if and when reunification occurs.
