The livelihood of the Mamuju comes primarily from farming and fishing. Mamuju farmers raise cattle and their primary forest product is ebony. Other Mamuju work as tradesmen, teachers, and nurses. The Mamuju home is simple, consisting of woven bamboo walls and a coconut leaf roof, and typically standing on a raised platform two meters off the ground. The Mamuju live in peace with their neighbors, demonstrating mutual respect, much like they do within their own families. Mamuju young people make their own choices as to whom they will marry. Women typically marry around the ages of 16-17, while men usually marry between 18 and 20 years old. They prefer big families. The Mamuju have religious leaders as well as government officials who the regency government appoints. The religious leaders hold great sway over the people, while government officials are effective only to the extent that the people believe them to be good leaders.

Ministry Obstacles: Important meetings are typically held in the local mosque. Such an environment keeps them from looking beyond Islam for spiritual truth.

Scripture Focus: "They read from the book, from the Law of God, clearly, and they gave the sense, so that the people understood the reading."

Pray for Mamuju disciples who will make more disciples. Pray for Mamuju elders to have dreams and visions of the risen Christ.
