New Tribes Mission, founded in 1942, focuses on its goal of preaching the Gospel to people groups that have never heard the message of salvation before. New Tribes Mission estimates that approximately 2,500 unreached people groups remain, out of a total of about 6,500 people groups in the world. New Tribes Mission believes that it is important for all people groups to have access to the Scriptures in their own language, so when a New Tribes missionary first contacts a tribe, the missionary’s initial goal is to learn the tribal language and culture. In many cases, the tribal language may not exist in written form, so the New Tribes missionary will need to produce such a form and teach it to tribe members before being able to provide them with a readable translation of the Bible. In addition to working on written translations, New Tribes missionaries also introduce tribe members to the contents of the Bible through oral presentations. Because the New Tribes Mission philosophy holds that tribe members need the context of the Old Testament in order to understand the story of Jesus in the New Testament, these presentations generally start with the Book of Genesis and move through the Bible chronologically. New Tribes missionaries contrast Biblical stories and tribal traditions, with the goal of increasing the relevance of Christianity to tribe members. For example, after one tribe heard the story of Moses and the ten plagues, in which God performed miracles targeting the spheres of influence of various Egyptian deities, tribe members immediately connected the Egyptian gods to their own tribal spirits and drew the conclusion that the Christian God was more powerful than their own. Ultimately, New Tribes missionaries attempt to found churches that will be led by tribe members, and New Tribes Mission has experienced encouraging success thus far.
