Part 10 - Joining God's Work

There are 16,600 people groups globally, with 7,100 considered unreached or least reached. Only 10% of the world's population are true believers in Christianity, while 30% have had virtually no exposure to the Gospel. Over the past 50 years, maps show the spread of Evangelical Christianity from concentrated areas in 1960 to a more widespread global presence by 2010, demonstrating the changes in how Christianity has spread during this time period.
