This book encourages Christians to think biblically: to distinguish which voices lead toward a godly life and which lead astray, and to embrace a mindset dedicated exclusively to an understanding of the world based on biblical truth. Edited by John MacArthur and written with the faculty of The Master's Seminary, it begins from the sufficiency and authority of Scripture rather than arguing toward it.

The contributors then work out that commitment across a range of fields: postmodernism and the nature of truth, gender, worship, psychology, science, education, history and civil government. Because each chapter is written by a specialist, the treatment goes further than a single-author survey would. Used as a worldview textbook and as a reference on particular questions.
