Across Africa, a cultic missionary group from Korea is working day and night to convert Christian believers—and is even swallowing entire churches. The group is called Shincheonji—although you may first encounter them using a name like “Zion Christian Mission Center,” or offering a free online “Equipped Bible Course.”

The global leader of Shincheonji is Korean pastor Lee Man-hee, who claims he is the one specially chosen by God and Jesus to “reign over the nations” and unlock the secrets of the Book of Revelation.
