Introduction / History

The Kosorong in Papua New Guinea are an indigenous people of the Morobe Province, particularly in areas of the Huon Peninsula. They are closely associated with the Borong language, sometimes also referred to as Kosorong, which connects them to a wider cluster of related groups in the region.

Their identity has been shaped over generations through life in this mountainous and forested environment. Like many smaller Papuan groups, their history is preserved primarily through oral tradition, family lineage, and shared community memory rather than written accounts.


What Are Their Lives Like?

Kosorong communities are rural and closely connected to the land. Daily life typically revolves around subsistence agriculture, with families cultivating gardens to grow staple foods. Hunting, gathering, and small-scale local exchange may also contribute to sustaining households.

Extended family relationships are central to social life. Cooperation among relatives and neighbors helps support farming, building, and community responsibilities. Elders and respected leaders play an important role in guiding decisions and maintaining social order.

The Borong (Kosorong) language is used in everyday communication and serves as an important marker of identity and cultural continuity. Tok Pisin is often used as a wider means of communication with other groups.


What Are Their Beliefs?

The Kosorong are associated primarily with traditional religious practices rooted in their cultural identity. These beliefs generally include an awareness of spiritual forces and influences connected to daily life and the natural world.

There is also a Christian presence among the Kosorong, and the gospel has been introduced to the community. However, continued growth in clear biblical understanding and consistent Christian practice remains an important need.


What Are Their Needs?

The Kosorong people would benefit from continued exposure to the gospel and from discipleship that leads to a clear and accurate understanding of Scripture. Where Christianity is present, there is a need for deeper spiritual maturity and faithful application of biblical truth.

The New Testament has been translated into the Borong language, providing an important foundation for engagement with God's Word. Continued use of Scripture, along with teaching and discipleship, will help strengthen the church.

There is also a need for faithful and biblically grounded leaders who can guide their communities with clarity and compassion. Strengthening families and encouraging Christ-centered living will support long-term spiritual growth.


Prayer Items

Pray that the Kosorong will come to a clear understanding of the gospel and place their faith fully in Jesus Christ, and none other.
Pray that believers will grow in their knowledge of scripture and live it out faithfully in daily life.
Pray for the development of strong, godly leaders who will teach truth clearly and shepherd their communities well.
Pray that the New Testament in the Borong language will be widely used and understood.
Pray that the Kosorong church will develop a vision to share the message of Christ with peoples in Indonesia and Malaysia.
