Brad Buser, co-founder of Radius International, spent over 20 years church planting among unreached people groups, particularly in Papua New Guinea. He shared his journey of being called to missions as a young Christian, the challenges of learning the language and culture, and raising his family in the jungle. Buser emphasized the importance of discipline, commitment, and reliance on prayer in taking the gospel to the unreached. He encouraged the audience to consider dedicating their lives to this work, while acknowledging the cost, and urged those not called to go to become "rope holders" who support missionaries through prayer and giving.
