Least Reached People Groups - A Missional Priority

In the heart of the globe lies the 10/40 Window, a rectangular region encompassing parts of North Africa, Asia, and the Middle East. This area is home to a significant portion of the world's population, including billions of individuals with limited or no access to the Gospel message. These communities are often referred to as "Least Reached People Groups" or, more commonly, "Unreached People Groups".

This article will shed light on the urgent need to reach UPGs in the 10/40 Window, highlighting the critical work that His Feet International is engaged in sharing the Gospel in these challenging areas. We will draw upon insights and data from reputable sources such as the Joshua Project to understand the unique challenges and opportunities presented by missions in this region. We will also explore practical ways that individuals and churches can support these efforts and contribute to fulfilling the Great Commission.

Let's embark on this journey to understand the complexities, the urgency, and the immense blessings of reaching Least Reached People Groups.

Understanding Least Reached People Groups

Least Reached People Groups are characterized by their limited exposure to the Gospel message. They may have few believers within their communities and often lack access to Bibles and biblical resources, churches, or trained pastors. These groups usually reside in remote or isolated areas, making it difficult for missionaries to reach them.

According to the Joshua Project, there are over 6,000 Least Reached People Groups globally, representing over 2 billion individuals. The 10/40 Window is home to most of these people groups, with some estimates suggesting that over 90% of the least reached reside in this region. Some examples of specific Least Reached People Groups in the 10/40 Window include the Pashtun people of Afghanistan, the Uyghur people of China, and the Yazidi people of Iraq. Each group faces unique challenges and requires tailored approaches for effective Gospel outreach.

Largest Least Reached People Groups

The least reached represent a vast mission field with billions of souls who have yet to hear the Gospel. Here's a look at the top 5 largest Least Reached People Groups based on population, according to the Joshua Project:

  1. Bengali Muslims (Bangladesh): With a population of over 135 million, Bengali Muslims are the largest Least Reached People Group globally. They reside primarily in Bangladesh but have significant populations in India and other countries.
  2. Japanese (Japan): The Japanese people, with over 117 million individuals, represent a unique challenge due to their cultural and religious context. While Japan is considered a developed nation, most of its population remains unreached by the Gospel.
  3. Shaikh (India): Numbering over 72 million, the Shaikh people group in India is predominantly Muslim and largely unreached. They are spread across various country regions and speak different languages, adding to the complexity of reaching them with the Gospel.
  4. Turk (Turkey): Turkey, a predominantly Muslim nation, is home to over 61 million Turks who have limited access to the Gospel. Political and cultural factors have contributed to the challenges of reaching this people group.
  5. Chamar (India): The Chamar people group, with over 54 million individuals, is one of the most prominent Dalit (formerly known as "untouchable") communities in India. They face significant social discrimination and are often excluded from mainstream society, making it difficult to reach them with the Gospel.

While these are just a few examples, the 10/40 Window is home to countless other people groups, each with its unique cultural, linguistic, and religious context. Reaching them may seem overwhelming, but the Great Commission compels us to make disciples of all nations, including the least reached.

The 10/40 Window: A Strategic Focus

10/40 Window Map - Detailed

The 10/40 Window is a geographic region situated between 10 degrees and 40 degrees north latitude, spanning from West Africa to East Asia. It encompasses various countries, cultures, and religions, with Islam, Hinduism, and Buddhism being the predominant faiths. The 10/40 Window is strategically vital for missions due to the high concentration of Least Reached People Groups and the spiritual needs of its inhabitants.

Historical and political factors, such as colonialism, conflict, and religious persecution, have contributed to the limited Gospel access in many parts of the 10/40 Window. However, despite the challenges, there have been significant breakthroughs in recent years, with many people groups experiencing Gospel movements and church-planting initiatives.

Challenges of Reaching Least Reached People Groups

Reaching the least reached presents a unique set of challenges that require innovation and a proper understanding of local contexts. Physical barriers, such as remote locations, rugged terrain, and lack of infrastructure, can hinder access to these communities. Political and legal restrictions on religious activities can also pose significant obstacles.

Persecution and hostility towards Christians are prevalent in many parts of the 10/40 Window, making it dangerous for missionaries and local believers. Cultural misunderstandings and communication barriers can complicate efforts to share the Gospel effectively. Furthermore, spiritual warfare and strongholds can create spiritual blindness and resistance to the message of salvation in Jesus Christ. Despite these obstacles, numerous examples of successful outreach to the least reached have demonstrated the power of the Gospel to transform lives and communities.

How His Feet International Serves the Least Reached

His Feet International is a missions organization dedicated to reaching Least Reached People Groups in the 10/40 Window. Our mission is to "make disciples of all nations" by proclaiming the Gospel, planting churches, and training local leaders. We employ a holistic approach to ministry, addressing communities' physical and spiritual needs. This includes providing emergency relief, education, and medical care alongside evangelism and discipleship programs.

Our strategies for serving Least Reached People Groups include:

  • Holistic approach: Addressing physical, spiritual, and social needs to demonstrate Christ's love in tangible ways.
  • Training and equipping local leaders: Empowering indigenous believers to lead and sustain their own churches and ministries.
  • Creative access strategies: Utilizing innovative methods, such as translation and media outreach, to overcome barriers and establish relationships with UPGs.
  • Partnership with local churches and organizations: Collaborating with existing Christian networks to maximize impact and ensure long-term sustainability.

We have been serving among Least Reached People Groups for over 20 years. In this time we have witnessed numerous salvations, baptisms, and church plants in some of the most challenging regions of the 10/40 Window. We have received testimonies from the field that attest to the Gospel's transformative power.

What is Currently Being Done

We are not alone in our efforts to reach the least reached in the 10/40 Window. Many other organizations, churches, and individuals are engaged in mission work in this region.

These organizations are working together to share the Gospel, plant churches, and disciple believers in the 10/40 Window. They employ a variety of approaches, including traditional evangelism, medical missions, education initiatives, and community development projects. The use of technology, such as satellite television, radio broadcasting, and online platforms, has also become increasingly important in reaching Least Reached People Groups.

Despite these efforts, reaching these people groups remains a significant challenge. The 10/40 Window's vastness, diversity of cultures, and complexity of political and religious landscape require ongoing commitment, collaboration, and innovation.

How You Can Pray

Prayer is absolutely vital in reaching the least reached. Below are several specific ways you can pray for the work of His Feet International and other organizations working in the 10/40 Window:

  • Pray for open doors and divine appointments: Ask God to open hearts and minds to the Gospel message and to provide opportunities for missionaries and local believers to share their faith.
  • Pray for spiritual breakthroughs: Intercede for the breaking down of spiritual strongholds and the release of God's power in the lives of UPGs.
  • Pray for provision and protection: Ask the Lord to protect missionaries and local believers and provide for their physical, emotional, and spiritual needs.
  • Pray for raising local leaders and church planters: Ask God to call and equip men and women from within Least Reached People Groups to lead their communities to Christ.
  • Pray for the translation and distribution of God's Word: Ask for God's guidance and provision in making the Scriptures available in the languages and formats that will reach the least reached.

Your prayers can significantly impact the lives of the unreached and least reached and advance the Gospel in the 10/40 Window.

How You Can Get Involved

In addition to prayer, there are many practical ways you can get involved in reaching UPGs:

  • Support His Feet International and other missions organizations financially: Your donations can help fund critical projects, such as church planting, leadership training, and emergency relief initiatives.
  • Volunteer for short-term or long-term missions: Consider using your skills and talents to serve alongside missionaries in the 10/40 Window.
  • Advocate for the least reached and raise awareness: Share information about the least reached with your church, friends, and family, and encourage them to pray and get involved.
  • Pray regularly for the least reached: Commit to praying for Least Reached People Groups daily or weekly, and consider joining a prayer group or online community focused on missions.

Every act of service, no matter how small, can have a ripple effect in fulfilling the Great Commission.


Reaching UPGs in the 10/40 Window is daunting, but it is also of the upmost importance. The challenges are real, but the opportunities are even more significant. As we serve together and trust the Lord to use our feeble efforts, we can witness the Gospel's transformative power in the lives of individuals and communities who have never before heard the precious name of Jesus.

Let us not be discouraged by the difficulties but rather inspired by the outcome promised in Scripture: a multitude gathered before the throne of the Lamb. Let us renew our commitment to pray, give, and go so that all nations may hear the Good News of salvation through Christ.

The harvest is plentiful, but the workers are few. Let us pray to the Lord of the harvest to send out workers into his harvest field. And let us be willing to be those workers however and wherever He may call us.
