The One True God is a workbook written by Paul Washer, intending not just to teach truth but to lead to an encounter with the living God. Beneath that goal the book aims to ground believers in orthodox Christian theology and the actual contents of the Bible. Students are encouraged to thoughtfully draw conclusions from the Scriptures rather than to merely absorb the principles, inferences, and illustrations set before them by the author. For this reason the book does not include such material and instead focuses on digesting the Scriptures directly.
