The title of this book originates from the self-description of Namibian Evangelists in their own words. African evangelists of the Rhenish Mission Society (RMS) played a crucial but mostly overlooked role in shaping the spiritual and social networks that transformed indigenous communities from the early nineteenth century. The author draws from a wide range of German, Namibian and South African archival sources that have been supplemented with a large number of interviews, to explore the history of the indigenous evangelists of the RMS. African supporters were often the first heralds of the new religion at remote villages and cattle posts before the white strangers made an appearance. The Namibian evangelists' familiarity with the traditional culture and the local vernacular endowed them with a credibility that many of the European newcomers found difficult to acquire. By interweaving mission and church history between 1820 and 1990 with a biographical approach, the author brings a hidden chapter in Namibian history to life. Hans-Martin Milk, born in southern Africa, grew up in Namibia and lived there until he left into Exile in the 1970s. He returned to Namibia after independence to teach in Kavango. During this time he started his historical research on the RMS and the Kavango.
