Delivering the Word of God in audio format to unreached people groups.

Reaching the Unreached

Every day, 66,000 people from unreached people groups die having never heard the Word of God. Today, 40% of all the people groups, or nations, in the world remain unreached. World Mission seeks to fulfill the Great Commission by providing the Word of God in an audio format to oral learners living in unreached people groups.

We define the unreached as a people group among which there is no indigenous community of Christians with adequate numbers and resources to evangelize without outside assistance. Following the Holy Spirit’s lead, our ultimate objective is to see these lost souls come to Christ and begin an indigenous church-planting movement.


Our focus is on the geographical area known as the 10/40 Window, where 90% of the population is considered unreached. Home to over 2 billion people, the 10/40 Window is the rectangular area of North Africa, the Middle East, and Asia between 10 and 40 degrees north latitude. Often referred to as ‘The Resistance Belt’, it includes a majority of the world’s Muslim, Hindu, and Buddhist population.


Jesus said to go and make disciples of all nations. But just what is a nation? A nation is a group of people bound together by the same culture, manners, customs, and other distinguishing features. While the world is home to just 195 countries, if we think in terms of nations, there are 16,500! World Mission prioritizes the 6,685 nations that are considered unreached. Despite being unreached, they receive less than 1% of all funding given to missions.


World Mission works closely with a network of national partners who speak the language and are working to create relationships within the indigenous communities where they minister. Because so many people in the 10/40 Window are oral learners, we provide these national partners with The Treasure; a solar-powered, hand-held audio player containing the gospel message in their own language.

Make a Difference

Though our efforts stretch across the globe, our impact would not be possible without the support of Believers here at home.


You can be a missionary without ever leaving West Michigan when you serve as a volunteer!

Our volunteers serve in their local communities and make a global Kingdom impact. Not only will you be demonstrating the love of Christ, but when you volunteer, you will be partnering with us in distributing the gospel and providing humanitarian relief to unreached people in the 10/40 Window.

For every 4 hours you serve as a volunteer, you generate enough revenue to distribute one audio Bible Treasure, impacting the lives of as many as 144 people for Jesus!


Your financial support enables us to continue to reach unreached people groups with the gospel message, allowing those who might otherwise never hear to learn about Jesus’ love and saving grace. Each Treasure costs around $50 but can reach approximately 144 people! We also welcome donations of lightly-used, quality clothing and household goods at our thrift stores.
