Do you know of the 1040 window?  If you prayed for North Africa, and the Middle Eastern Nations captive to Islamic Rule and Asia including India and China, You would be touching the majority of the unreached by the Gospel peoples in the world.  http://www.30-days.net/         Rev 5:6-10 "And between the throne and the four living creatures and among the elders I saw a Lamb standing, as though it had been slain, with seven horns and with seven eyes, which are the seven spirits of God sent out into all the earth. And he went and took the scroll from the right hand of him who was seated on the throne. And when he had taken the scroll, the four living creatures and the twenty-four elders fell down before the Lamb, each holding a harp, and golden bowls full of incense, which are the prayers of the saints. And they sang a new song, saying, "Worthy are you to take the scroll and to open its seals, for you were slain, and by your blood you ransomed people for God from every tribe and language and people and nation, and you have made them a kingdom and priests to our God, and they shall reign on the earth."
