Missionary Doctor to the Congo Dr. Helen Roseveare was serving the Lord at an isolated hospital in the jungles of the Belgian Congo, preaching, teaching and doctoring. In 1960 the colony became an independent nation: Zaire. But four years later, the Simba rebellion threw the country into anarchy. Rebels began a reign of terror, and missionaries were under constant threat of personal assault and death. Finally, as government troops advanced, Dr. Roseveare and others were held as hostages by the Simbas. Helen Roseveare traveled all over the world, speaking to people about Jesus Christ and the need of Christians to care about others enough to share the gospel.
