Small is not the same as absent

In several of these nations the church is small, hidden and growing. Iran is widely reckoned among the fastest-growing churches anywhere despite a near-total ban; Algeria's Kabyle region has seen the clearest turning to Christ in North Africa in a century. A low percentage describes access and cost, not the end of the story.
