General Prayer Requests
For 10x40 Window Countries:

Pray that God will give Christians
who are living in the 10x40 Window new ideas of how they can reach the lost in their part of the world.

1. Why is the 10x40 Window important?
      Jesus said in Matthew 24:14, "And the Good News about the Kingdom will be preached throughout the whole world, so that all nations will hear it; and then, finally, the end will come." This area of the world needs to be reached with the gospel so that all nations/peoples will hear about Jesus before He returns.
2. Who lives in the 10x40 Window?
      4 billion unreached people live in the 10x40 Window, that's 2/3 of the world's total population. Most of the nations in the window are closed to missionaries or Christians, which means missionaries cannot live there. The easiest way to know who lives in the window nations is to remember how to spell T-H-U-M-B.
3. What is T-H-U-M-B?
      To help you remember the people groups who live in the window, try this...
      T - Tribal people (All over Asia, mostly in remote areas)
      H - Hindus (India/Indonesia)
      U - Unreligious (Chinese and communist countries)
      M - Muslims (Middle East and North Africa Nations)
      B - Buddhists (Middle Asia, Thailand, Cambodia, China, etc.)
