I think there are both challenges and opportunities [for the modern church]. The people groups who are still unreached or unengaged present huge challenges. At the same time I see Millennials and ensuing generations as uniquely equipped to be part of seeing every language and every people group be transformed by knowing God through His love and His wonderful words of life. It will undoubtedly take new strategies; we need to welcome change. The work will surely be fraught with challenges, but I am confident that Revelation 7:9 is true, and that one day we all will be part of that great gathering of people from every nation and language people and tribe standing before the throne of the Lamb. Together on that day we all will all shout with a great voice: 'Salvation belongs to our God who sits upon the throne and to the Lamb!'
