Africa
From ReformedWiki.org, the wiki for Reformed Christianity
Africa is a continent. In recent years, Christianity has experienced rapid growth in Africa, particularly in Sub-Saharan Africa. The number of Christians in Africa has increased dramatically over the past century, with the continent now home to over 600 million Christians, making it one of the fastest-growing regions for Christianity globally.
It has a land border with Asia to the east and is disconnected from Europe by the Mediterranean Sea.
