It has been called the “surprise story” of modern missions–the emergence of ‘Christian Africa’ (Bediako, 2000:3-4). In the last century, Christianity in Africa has seen the fastest numerical growth of any continent ever in church history. Down in South Africa, we in the Baptist Union have enjoyed a taste of this rapid church growth. But such expansion also brings unique challenges. In this article I would like to explore these challenges, first on a wider scale and then zooming in on the BUSA, followed by some biblical solutions and suggested strategies. We must take a hard look at three critical issues that should compel us to launch a church-strengthening movement in the BUSA that will exalt Christ and bless the nations for generations to come.
