'The best biblical study there is on the nature of missions. The best, however, has become better! After building a solid biblical base, Piper confronts some burning issues in missions today in a way that is both spiritually nourishing and inspiringly readable.'

- Ajith Fernando, National Director, Youth for Christ (Sri Lanka),

'If I had to choose only one book on missions, Let the Nations Be Glad! would be it - precisely because it's about so much more than missions. The book's relentless God-centred focus, with its stress on worship as the "fuel and goal of missions", provides the crucial biblical counterpoint to the anthropocentric drumbeat of our day. Don't read it unless you're willing to have your eyes reopened to the highest possible motive for being about the business of reaching the world for Christ.'

- Duane Litfin, President, Wheaton College,
