““But how then to explain the failures? What if Christians do make disciples of all nations, but subsequently lose them or their descendants? How can we account for such devastating reversals as the annihilation of the church in North Africa, the crushing of Catholic missions in Asia, and, above all, the strangulation of the faith in the Middle East? Presumably, each of these failures happened regardless of countless fervent but unanswered prayers. In terms of its global reach, only in very modern times has Christianity resumed the span that it had achieved a thousand years ago. Christianization, obviously, is not an inevitable process, nor a one-way road.””
