Hope this Helps: Praying for Unreached People Groups
A great practice for youth ministries is to pray for unreached people groups around the world. The Joshua Project publishes great material for prayer in this area.
“Joshua Project is a research initiative seeking to highlight the ethnic people groups of the world with the fewest followers of Christ…From this overall ethnic people group list, a subset of unreached / least-reached peoples has been identified based on the criteria of less than 2% Evangelical and less than 5% Professing Christian. This subset helps focus attention on the unfinished task of the Great Commission. We desire that this list be used by mission agencies, denominations, churches and missionaries to accelerate the Gospel’s advance into each of the least-reached people groups.”
