Unreached Muslim people groups
There are about 220 Muslim peoples around the world with over 100,000 members each, and these peoples have no local committed Christian witness. In addition, there are no known believers who are specifically planning to take the Gospel of the Kingdom to them. A short list of some of the last of the unreached Muslim peoples is on this page. In addition there are huge numbers of Muslims peoples where there is a small Christian witness, but the Muslims still have never heard the Gospel in a meaningful and culturally adapted way. This is true of millions of Arabs in the Middle East as well as millions more in Africa and Southeast Asia.
Jesus said, “This Gospel of the kingdom will be preached in all the world as a witness to all the nations, and then the end will come” (Mt. 24:14). The end of the age and the dawning of God’s new world will not come about before all people from different religions and cultures have had an opportunity to hear and to respond to the message.
Pray for those Muslims among whom there is still no Christian witness, that at this Ramadan they may be visited by God in dreams and visions, connect with TV and radio programmes and hear the good news that there is certainty in relationship with God.
