Speaking from the Zambian perspective,I must admit that Christianity here (and generally across Africa) is 752,000 square kilometers but only 1 centimeter deep. With the spread of Nigerian junk theology, it seems to me that Africa is sliding back into the dark ages with Ministers of historic Protestant churches such as Presbyterian or Reformed Church promoting Nigerian prophets. that is the sad reality.

Concerning the missionaries who come to Africa, very few are sincere but many are tourists. I have met a couple of missionaries from Mission To the World, a missionary agency of the Presbyterian Church in America (PCA). I can bear witness that these are doing a great job but they are mostly operating in South Africa. Other missionary agencies tend to be more interdenominational, especially here in Zambia and therefore their effectiveness depend largely on the doctrinal dispositions of the individual missionaries.
However, I must state also that our people tend to respond more favorably to American missionaries because they bring with them material benefits which local pastors cannot afford. So sometimes the numbers of "converts" reported by missionaries are often true but many of these conversions are not genuine.

In my opinion, the best way to go is for American churches to partner with the few faithful local churches in the work of Church planting. Here in Zambia, a model example is what Kabwata Baptist Church (KBC) is doing in partnership with American churches. KBC sends local/indigenous missionary pastors to plant churches instead of having white missionaries coming over to do the work.
