The 10/40 Window

More than 90% of the unreached people groups in the world today are located within the “10/40 window” more than 5,100 tribes and ethno-linguistic groups with little or no gospel witness. Of the world’s 50 least-Christian and least-evangelized countries, all 50 are located within this region! In the highlighted area above, there are more than 90% of the world’s remaining unreached people groups, and all 50 of the world’s least evangelized countries. These countries are the focus of the Back to Jerusalem movement. As you read these pages, please remember that the Back to Jerusalem movement is not a crazy pipe-dream of a few fanatical Christians that may or may not happen. It is something that is already happening! Right now there are already hundreds of Chinese missionaries working outside China in the Middle East, North Africa, Central Asia, the Indian Subcontinent, and Southeast Asia. Thousands more are in training, learning languages such as Arabic and English that will be put to use on the mission field.
