An open secret is that North Korea is 100 per cent against Christians. It is vying to become the worst place on earth for Christians to be.
It is a well-known fact that it is the most militantly atheistic country in the world. For the past 50 years, North Korea has sought (somewhat successfully) to eradicate Christianity from the country. Nearly all outward vestiges of religion have been wiped out and what exists is under tight government control.
Often, refugees will flee North Korea and try to find help in China. The Christians there, especially, work very hard to provide food, shelter and aid to these refugees. A number of the refugees find Christ but the Chinese government deports North Koreans back to their country. If North Korean officials discover the identities of these refugees, they will arrest them and their families.
We must keep an open mind and not trust countries like North Korea. A little prayer will help too.
