You may be aware that there are around 6,000 Unreached People Groups (UPGs) in the world - people groups with less than 2% Evangelical Christians. But within these UPGs are just over 4,000 Frontier People Groups - people groups with less than .1% Christian of any kind. These are the groups where pioneer work is still needed.
Half of the population of these FPGs is concentrated in 31 groups - totalling nearly 900 million people. God once said of Nineveh, "should I not have concern for the great city of Nineveh, in which there are more than a hundred and twenty thousand people who cannot tell their right hand from their left" (Jonah 4:11). How much more do you think he's concerned about 900 million people without any realistic chance of hearing the Gospel before they die?
Pray for the 31 is a movement to inspire and equip prayer for these 31 key FPGs. Check out the site for more information or to order a prayer guide! There's also a downloadable PDF.
