What new insights concerning human nature may be discovered when theology and psychological science are brought together? This is the question that inspired the TheoPsych project and that continues to encourage new, innovative research. But it's a daunting task to responsibly integrate a whole new field of research into the one you've already mastered. This primer serves as the foundation for gracefully incorporating this new territory. Keeping the word count relatively low, Justin Barrett gives a surprisingly comprehensive overview of the field of psychology, keeping in mind an audience of theologians and ministry leaders, and gesturing to key resources for deeper study along the way.
