So when do the various African Christians start sending missionaries to the savages to their north?
It will happen. South Korea already sends out large numbers of missionaries, and other formerly “mission field” countries are following suit. As Christian influence in Europe and the US decline we’ll see a reversal of missionary patterns. Money to support mission work is a big factor but I could see some interesting partnerships develop if western mission agencies remain adequately funded, but lack trained westerners to send out.
