Dr. David Garrison, executive director of Global Gates, traveled a quarter-million miles throughout the Muslim world gathering more than a thousand interviews from Muslim-background believers in burgeoning movements to faith in Jesus Christ. He asked these baptized Muslim background believers the simple question, “What did God use to bring you to faith in Jesus Christ? Tell me your story.” The result was the groundbreaking book, A Wind in the House of Islam. Garrison discovered that we are living in the midst of the greatest turning of Muslims to Christ in history!

Where Missionaries are Most Needed in North American Cities

Where should Christians prioritize work and prayer to see the least-evangelized peoples in North America reached with the gospel? Below is a list from a working spreadsheet that attempts to determine the most significant unreached people group communities in North American cities where missionaries are needed. The list is sorted using an overall significance score based on a matrix of weighted factors including global status of evangelical Christianity, population size in the city, ministry engagement in the city, same culture Christians in the city, and the global significance of the people group’s presence in the city. To access the working spreadsheet on google docs, click here. Within the spreadsheet, you will see an explanation of the factors above, the weight assigned to each factor, and how the people groups scored for each factor. Feel free to insert comments if you have input on the table’s data to make it better. Also, if you have information (even if incomplete) on an unreached people group in a North American city that should be added, please submit the information through this form (the people group must number at least 5,000 in the city to be included).
