Of the world's 6,500 people groups, 2,500 are still unreached. New Tribes Mission helps local churches train, coordinate and send missionaries to these tribes. I met with Jack Crabtree a few months ago, and he shared his heart for Papua New Guinea and the unreached nations. I see he and his family are trying to be faithful by moving there soon and they are in the process of raising more support to help them be sustainable while they focus on their ministry in PNG. I offered to do a piece that would help share the vision for what NTM is trying to do in PNG and to see the faces that God is bringing himself to through people like the Crabtree's.
Please take the time to visit Jack's website and get connected. http://blogs.ntm.org/jack-crabtree/
