Linguistic translation is needed both locally and globally. The Bible has many translations which are accessible through smart devices and sometimes paper copy, however many other christian reading materials are only available in English.
People who live in places like this have no access to any technology from which they can read or hear a Bible in their language. Also, the absence of a written language is not uncommon in many third world countries.
