Every aspect of North Korean life is controlled by the state, which believes that there is no higher authority than Kim Jong-un. Christianity threatens this belief and must be crushed. Tens of thousands of Christians are imprisoned in labour camps, yet the church is growing. There are 300,000 courageous believers, many not even telling their children, who live under constant surveillance by authorities looking for anything that might threaten the regime. There are even rewards of a new home or better job for anyone who helps discover Christians. Every citizen must report to a ‘neighbourhood watch’ system any absence from home, or a neighbour neglecting to clean the portrait of Kim which everyone must have on their walls.
