Piper’s book, Think, is a great introduction to Christian thinking. In this book, Piper attempts to kindle the desire for Christian thinking among evangelicals. He does this by sharing his personal experience, by defining the practice of Christian thinking, and by answering the criticisms of the relativists and the anti-intellectuals. It is a helpful antidote to the excesses of relativism and anti-intellectualism. The seasoned Christian thinker, however, will find little here which is ground-breaking. Relativists may find Piper’s section on relativism lacking in thorough argumentation. Overall, Think is a good read which would be helpful to encourage Christians to think about their faith in a deeper way.
