The Bibleless Peoples Prayer Project is a movement created by Wycliffe Bible Translators to raise up prayer for the 1600 people groups (with about 160 million people) around the world without a Bible in their heart language. 

God promises that when his word goes out, it won't return empty but will accomplish his purposes (Isaiah 55:11) - in this case, the purpose of bringing unreached peoples to him.

Most of us won't necessarily go to a different nation or people group to take the Gospel to them and make disciples, but we can still participate in Jesus' Great Commission through prayer - especially for those most in need of God's Word.  Join the movement!
