The 10/40 Window helps describe a wide region where many communities have limited access to the message of God’s love—and where GFA World serves through practical, compassionate ministry.

The 10/40 window is a rectangular area between about 10 degrees and 40 degrees north latitude. It covers North Africa, the Middle East and Asia.[1] This window is home to some of the world’s most remote people. It includes most of the world’s Muslims and also Asia’s traditional religions. Because this region includes many countries in the Middle East and Asia, it can be hard to picture as one place. Yet the phrase 10/40 Window represented a simple way for many believers to remember a shared concern: access to the Gospel. In that sense, the 10/40 Window is home to communities where many people may never have a clear chance to learn about God’s love.

This has earned the region another nickname—“The Resistant Belt.” A recent revision to the official list of countries has included several more that are close to the area, rather than completely within the 10- and 40-degree latitude lines. These countries also have large populations who have never heard the good news of God’s love for them. Some writers have called the resistant belt a reminder that sharing God’s love should be done with humility, patience, and respect.

With the revised list of the 10/40 window, facts and statistics have become even more sobering. Joshua Project estimates about 5.44 billion people in 8,572 people groups live within the revised 10/40 Window.[2] It also reports that about 3.45 billion people are in people groups it tracks as having very limited access to the message of the Gospel—such as the Shaikh, Yadava, Moroccan Arabs, and Burmese.[2]

The need for truth is great in this window. It is even greater because the region is historically significant in God’s plans. Much of Scripture takes place in this global rectangle. Israel is in the middle of the window: God’s Promised Land and God’s chosen people. For many believers, that history also connects with the Great Commission—a call to follow Jesus Christ in word and deed, with compassion and respect.

Biblical history shows that, even with God’s direction, the people of the region drifted away from Him from the very beginning. This includes Adam and Eve in Genesis 3. It includes the actions that led to the Flood. It also includes the Tower of Babel. The building of the tower caused the people to be dispersed, and it eventually led to the formation of the very peoples and groups that remain in this area today. This is one reason the Bible’s story can feel personal here: it speaks to families, languages, and communities across generations.

So, ministering in this cradle of so many civilizations is a major goal for various organizations. There is no shortage of work in the 10/40 window. Missionaries may minister in one of the fifty least reached megacities in the world. Or they could make efforts to help the poorest of the poor. Serving people across deep histories, cultures, and faith backgrounds can be extremely challenging. Islam spreads across the top of Africa and the Middle East.

Traditional Asian religions reign over South Asia as well as Southeast Asia. While China is officially an atheistic country, it too has deep traditional Asian religious roots.[2] Asia’s population is about 58.74% of the total world population, which helps explain why this region often touches a majority of the world.[3] The sheer and growing size of these populations—and their devotion to traditional Asian religions—makes missionary work in the region difficult but increasingly vital.

GFA World is an organization especially devoted to reaching this part of the world. Since 1979, GFA has sought to serve the “least of these” in Asia, and now in Africa as well. This often happens in places where no one else is serving.[4] The goal is to share God’s love with those who have never heard the Gospel before. This includes many people living within the 10/40 window. That long-term focus is why the list of countries in the 10/40 Window matters to many readers—because it helps them pray and give with a clearer picture.

The primary ways in which GFA accomplishes this mission are through:

  • partnering with national missionaries,
  • children’s ministry,
  • developing communities, and
  • offering disaster relief and care.[4]
    These ministries are meant to show God’s care in practical ways, without pressure or coercion.

National missionaries are from the regions where they minister, so they are uniquely positioned to know the people and the culture. This allows them more freedom than an outsider would have. It also means they have an intimate understanding of how to communicate the Gospel effectively. For a Christian missionary, that local understanding can mean safer relationships, clearer communication, and deeper trust over time.culture. This allows them more freedom than an outsider would have. It also means they have an intimate understanding of how to communicate the Gospel effectively.[7]

Our Child Sponsorship Program ensures children living in some of the poorest nations of the world have vital essentials like: food, clean water, hygiene products and training, healthcare and education. Children learn how to read and write. They also learn that God loves them.

GFA works to develop communities with gifts such as livestock that can provide continuing sources of income. GFA also provides wells for fresh water access and hygienic toilets.

Income generated by animals and things like sewing machines help to lift families and communities out of poverty. Clean water improves health and the ability to work. All of this shows people how much God cares. When disastrous floods or earthquakes strike, GFA World is on the ground. We help to rescue people, care for survivors and show them God’s loving-kindness. GFA’s emergency supplies, counseling and help to rebuild all point people to their Creator.

All GFA’s ministries are especially vital among the 10/40 window nations, which are in desperate need of the Gospel. GFA already ministers in over twenty countries, including Bangladesh, Sri Lanka, and Nepal.[4] All three appear on the revised list of those nations within the window who have yet to hear of Jesus.[2] As GFA continues expanding ministry into Africa, our impact within the 10/40 latitudes will grow.

If GFA’s work in this region interests you, consider partnering with us. It only takes $45 a month to help sponsor a national missionary. Sponsoring a child is a mere $35 monthly. Even if a monthly payment is not possible, a single donation of any amount can help GFA provide food, care or relief to a person in desperate need of God’s love.

There is still so much to do to minister to the unvisited people of the 10/40 window. GFA relies on Christians all over the world to make our ministries possible. If you are not able to give right now, you can still pray that families will hear the Gospel in ways they can truly understand, and that God will guide every step of this work.
