From the perspective of the sociology of missions, this study explores the Korean Christian Zionists' mission work after 9/11. The current Pentecostal success in South Korea has spurred the nation to send more missionaries abroad than any other country except the United States. As America has been losing the trust of the world since 9/11, some evangelical fundamentalists argue that Korea should take over the initiative of world mission from the United States. The Jerusalem Jesus March in 2004 and the South Korean hostage crisis in Afghanistan in 2007 have served to admonish Korean churches to hastily reconsider coercing their missionaries to proselytize in dangerous areas such as Islamic lands. This study unfolds issues such as “spiritual subjectivism” and “Korea-centrism”, illustrated by the Jesus March incident and the Afghan controversy, and suggests that the expansionism of Korean Pentecostal/evangelical missionaries taken up with the idea of “global spiritual conquest” is a manifestation of “Korean Christian Zionism”.
