  1. It’s so important to make people aware of the 10/40 window – this is a great article!

    I have such a burning desire to get back there – I pray for the opportunity each day.

    God Bless

  2. Chad…

    I know that God is aware of the burning desire of your heart to venture back into the 10/40 and will honor that desire. Please know that I will pray with you for both the opportunity and the resources.


  3. Great Article. I forwarded to all on my email list. The things I don’t know about the world surprises me and I have travelled and seen things I would not have chosen to see. Please pray for me Omar. I hope someday to be healthy and financally able to go on a mission trip with you and do more good for our church. I am totally committed to our Lord but still don’t understand how everything works with mission work. Thank You, Sharon Albritton

  4. Sharon…

    Thanks for spreading the word about the 10/40 Window. Please know that you are in my prayers. I trust the Lord will enable you to participate in one of our international missions initiatives at some point. In the meantime, please continue to pray for the many people groups in the 10/40 Window. You can learn more about these people groups at The Joshua Project website.


  5. Our experiences have found that the traditional ‘way’ of missions outreach in restricted access nations may not be the only way… we are reaching Muslims and seeing them saved in our innovative community projects such as conducting literacy classes for children, activity centers and camps for youth, or basic seminars. The harvest truly is plenteous!

  6. My heart breaks for everyone living in the 10/40 window. I’ve felt the call to be a missionary for a long time and I’ve been working around where I live with religions that dominate the 10/40 window. I want to go to the 10/40 window, but I’ve never been on a mission trip. I feel a burn to make it to the 10/40 window but I don’t know how…

  7. Kat…

    Thanks for sharing your heart for the nations. We live in a day of unprecedented opportunity to reach out to unreached peoples.

    First, we can go into all the world. If your church does not provide opportunities for you to participate in short-term mission trips to the 10/40 Window, then you can contact organizations like Innovative Mission Opportunities ( This is one of many organizations that mobilize teams to go to the unreached.

    Second, all the world is coming to us. Peoples from 10/40 nations are coming to America offering Christ-followers with many opportunities to make meaningful connections with them.

    Don’t lose your passion for the peoples of 10/40 nations. Look for ways to connect with these precious people groups both here and around the world.
