Our aim in going to an unreached tribe is to share the good news of what God has done through Jesus Christ for the world and for the sake of their salvation. This will take time. We will learn an undocumented language, create an alphabet in order to teach them their spoken language and give them a written language. Once this process is complete we will be able to share with them where they have come from and what their creator has graciously done on their behalf. They will, for the first time in their history, hear, see, and hopefully experience the liberating news of Jesus Christ.
"To him all the prophets bear witness that everyone who believes in him receives forgiveness of sins through his name." Acts 10:43
