Communities where He is least known

The Deaf

There are an estimated 72 million deaf people scattered across every nation on Earth, whose primary means of communication is one of the world’s 350 sign languages. Only about 2% of them follow Jesus. Not even one sign language group has the entire Bible in their first language. Guinea’s deaf population (around 27,000 people) mainly uses an assortment of “home signs,” which only family and close friends understand. This hinders them from learning about Jesus in a way they can understand.


Muslims of Upper Guinea

Upper Guinea has been home to the Maninka people for centuries. More recently, people from Guinea’s largest ethnic group, the Fulas, have moved in and now call Upper Guinea their home. Each group is fiercely proud of its language, culture, and religion. Ethnic tensions surface from time to time. Those who consider following Jesus fall under intense family and social pressure to remain faithful to Islam. Despite this pressure, God is working, and there has been increasing interest what the Bible says. Micro SD cards with God’s Good News in Maninka are being widely distributed.
