World Missons

“How then will they call on him in whom they have not believed? And how are they to believe in him of whom they have never heard? And how are they to hear without someone preaching? And how are they to preach unless they are sent? As it is written, ‘How beautiful are the feet of those who preach the good news!” –Romans 10:14-15

Unreached: An unreached or least-reached people is a people group among which there is no indigenous community of believing Christians with adequate numbers and resources to evangelize this people group. Most agree that this is less than 2% Evangelical Christian.

What Can I Do?
The following list is simply suggestions on what you can do. My advice is to get on your face before God Almighty and ask Him to show you what He wants YOU to do.

PRAY! Below are some general prayer requests that you can pray. Some of us are called to GO and others are called to SEND, but ALL are called to pray!
Buy a world map, put it up in your house and pray over the countries! If you laminate it you can write prayer requests that correspond directly to a specific country and erase and re-write as prayers are answered and new ones arise.
Pray for God to give you a burden for a specific country or people group, learn about them and what their needs are, and lift them up in prayer daily.
Sponsor a missionary to go into the 10/40 Window and proclaim the Gospel of Jesus Christ to the unreached.
