Perhaps all the statistics I’ve shared thus far can be best summed up by some remarkable figures released by Ralph Winter. In a chart labeled “The Diminishing Task,” he plots the number of evangelical Christians per non-Christians in the world. These figures do not include under either category people who are just nominal Christians. In the year 100 there were 360 non-Christians for every evangelical Christian. By the year 1000, there were 220 non-Christians for every evangelical. By the year 1900, there were only 27 non-Christians per evangelical. By 1950 that number had shrunk to 21 non-Christians per evangelical Christian. And in the year 2000 there were 7 non-Christians for every evangelical believer in the world. Even if you add in all the nominal Christians as well as targets for evangelism, that still means there are only about 9 unbelievers to be evangelized for every believer.
