Beyond its geography, the 10/40 Window is significant for several reasons: it is the most densely populated region in the world, contains many of the poorest areas, includes the majority of countries where Christians face severe persecution, and is home to all major world religions.
Christian persecution within the 10/40 Window is a serious and pressing issue. In many countries, Christians face severe restrictions on their religious freedoms, from social discrimination to violent attacks and imprisonment. Governments in some of these nations enforce strict anti-Christian laws, making it illegal to practice Christianity openly or to share the faith with others.3
The 10/40 Window is also the birthplace of major world religions such as Islam, Hinduism, Buddhism, and many indigenous faiths. It includes countries with the largest Muslim populations like Indonesia and Pakistan, and nations where Hinduism and Buddhism are predominant like India and Thailand. These religions influence the culture, society, and politics of the countries, often resulting in complex interfaith dynamics. The presence of these major religions in such close proximity emphasizes the importance of the 10/40 Window as a key location for missions.
Only 3.4% of missionaries around the world serve within the 10/40 Window. That's 3.4% of missionaries for the 97% of the world's unreached people.4 Let's do the math...
So a city the size of Nuremberg would have 2 Christian workers to reach an entire city who has never heard of Jesus. Now that's a task!
Only God knows the exact numbers, and He knows each of these people by name. He also knows how many people are needed to go so that everyone has the opportunity to hear about Him. And that's why He's not calling a select few. The Great Commission is a command to all Christians.
According to the Center for Study of Global Christianity, 270 billion dollars are given to Christian work by believers globally each year (this is way less than tithing, just 1.76% of that same group's income is given to Christian work). Of what is given, 5.6% goes to missions. But only 0.1% makes it's way to work in the 10/40 Window.5
The Great Commission calls us all to be involved in seeing Jesus made known throughout the whole world. And maybe not every one of us has the ability to go and move to the 10/40 Window to serve. But we all have finances to give, and we definitely all can pray.
