Egyptians speak Arabic. Egypt is home to both the fastest growing population in the Middle East and the largest Christian population in the Arab world. It remains a strategic location for Christian activity across North Africa and the Middle East. There are many well-established evangelical churches and parachurch ministries focused on reaching both nominal Christians and Muslims with the gospel inside Egypt. Several of these groups also send Arab missionaries across the region. Overt Christian activity can result in persecution, but there is much to be excited about as the church grows in Egypt and establishes a regional base of missionary activity. Sunni Islam is the majority religion, but 10 percent of Egyptians are Coptic Christians. Various extremist groups operate in Egypt, including the Muslim Brotherhood and the self-proclaimed Islamic State (ISIS). The government does little to prevent attacks on Christians and sometimes beats or imprisons those who are outspoken about their faith.
