The term "unreached people" is not explicitly found in the Bible, but it refers to groups of people who have little to no access to the Gospel of Jesus Christ, particularly those who are not part of a Christian community or do not have the Scriptures available in their language. This concept is closely aligned with the biblical mandate for evangelism and missions, as seen in passages such as Matthew 28:19-20, where Jesus commands His followers to "make disciples of all nations." The Greek word "ethne," often translated as "nations," indicates people groups or ethnicities, underscoring the importance of reaching diverse cultures.In the Old Testament, God’s plan for Israel included a vision for the nations (Isaiah 49:6), indicating that His salvation was intended for all people, not just Israel. The New Testament further emphasizes this universal call, as seen in Revelation 7:9, which depicts a great multitude from every nation, tribe, people, and language standing before the throne of God. Therefore, the concept of unreached people aligns with the biblical narrative of God's desire to see all nations come to know Him, highlighting the need for ongoing missionary efforts to reach those who have yet to hear the Gospel.
