For many years it was believed that Dr. David Livingstone, famed missionary to Africa, had just one convert. The man was a chief from Botswana named Sechele whom Livingstone wrote off, stating that the chief had backslidden. Sechele, however, might in fact have been one of Africa’s greatest evangelists. Missionaries arriving to work with the Zulu Ndebele tribe in 1859 were surprised to find that they already practiced regular Christian prayers. Sechele had taught them to read the Bible and many of the Bakwena had become believers in Jesus.
