Missionaries from the West like to hit the ground running to solve as many of other people’s problems as possible in the increasingly short term they have available for service. Hang on, says Jim Harries! After twenty-four years in Africa, observing how poverty, traditional practices, dependency, and misunderstandings continue, Harries asks, what is the point of bringing solutions that local people cannot reproduce? Harries challenges missionaries and development workers to counter dependency on the West by engaging in sustainable ministry that local people can imitate. This requires some Westerners to work on the basis of local languages and resources, a practice known as vulnerable mission. Rooted in personal experience, founded in a postmodern appreciation of language, drawing on anthropology, based in Christian theology, Harries provides a case for the necessity of vulnerable mission in the twenty-first century.
