The 10/40 Window is one of the most significant concepts in global missions, yet it remains unfamiliar to many. Stretching from North Africa across the Middle East and into Asia, this region is home to the majority of the world's unreached people groups.
For organizations like Mosaic International, which are committed to equipping local churches and communities to be catalysts for transformation, understanding the importance of the 10/40 Window is crucial.
What Is the 10/40 Window?
The term 10/40 Window was first coined by Christian missionary strategist Luis Bush in 1990. It refers to a rectangular area of the world between 10 and 40 degrees north latitude, encompassing parts of Africa, the Middle East, and Asia. This region is home to over 5 billion people, including the largest populations of Muslims, Hindus, and Buddhists.
Why Is the 10/40 Window Important?
High Concentration of Unreached People Groups
More than 90% of the world's unreached people live within the 10/40 Window. These are communities that have little to no access to the Gospel, with entire generations growing up without ever hearing about Jesus Christ.
Spiritual Strongholds and Resistance
Many of the countries in the 10/40 Window have historical and political barriers to Christianity. Governments in some nations actively suppress Christian evangelism, making missions work difficult and, at times, dangerous.
Extreme Poverty and Humanitarian Needs
The 10/40 Window is home to some of the world’s poorest nations. Many people struggle with inadequate access to clean water, healthcare, education, and economic opportunities. Poverty and spiritual lostness often go hand in hand, making holistic mission efforts crucial.
Historical and Biblical Significance
Many of the world's major biblical events took place within the 10/40 Window, from the Garden of Eden to Jesus’ ministry in Israel. The region remains central to the unfolding of God’s redemptive plan.
Mosaic International’s Role in the 10/40 Window
Mosaic was founded on the belief that sustainable transformation begins with strengthening the local church. Rather than imposing outside solutions, we work through indigenous leaders who already understand the culture, language, and specific challenges of their communities.
Discipleship: Equipping Local Believers
Discipleship is at the heart of what we do. By training local church leaders, we ensure that the Gospel is shared in a way that is both effective and culturally relevant. Through mentorship programs, Bible training, and leadership development, we empower local believers to share the Good News boldly.
Mobilization: Sending Out Local Missionaries
Rather than relying solely on foreign missionaries, we equip local believers to become missionaries in their own nations and beyond. This multiplication strategy allows for the Gospel to spread organically, even in places where Western missionaries cannot go.
Relief: Meeting Urgent Needs
The 10/40 Window is home to communities affected by war, famine, and natural disasters. Our relief efforts provide emergency food, medical care, and shelter while laying the foundation for long-term development.
Development: Creating Sustainable Solutions
While relief efforts address immediate needs, development focuses on long-term solutions. From vocational training to microfinance programs, we work to break the cycle of poverty in a way that preserves dignity and fosters self-sufficiency.

The Great Commission and the 10/40 Window

At Mosaic International, we believe that transformation happens when people come together in faith, action, and generosity. By strengthening the local church, equipping leaders, and mobilizing believers, we are seeing lives changed and communities renewed.
