In 1900 about eight percent of the world's population lived in sizable cities. The British Empire once included more than fifty nations, and now all those nations live in London. The British are not prepared for all this, nor are the missionaries of the United Kingdom. There are more Muslims in the cities of the U.K. than there are Baptists and Methodists combined. In cities like Bradford, near Leeds, over eighty percent of the population is now of Asian origin.
Mission now goes in both directions.
Consider the cities of Germany. More than a hundred years ago the Germans built a railroad to the Bosporus. Now hundreds of thousands of Turks live in German cities. A more dramatic pluralization of what was once a homogenous community could not be imagined. Some eighty million Chinese live outside of China.
