Biblical Truth Matters by Dr. Gary J. Harloffs discusses essential theological issues, structured into three main chapters. The first chapter, The Spiritual-Physics of Salvation, explores the complex relationship between spiritual beliefs and physical realities in the context of salvation. The second chapter investigates The Apostle's Creed - 'He Descended into Hell', analyzing the historical and doctrinal significance of this controversial statement. The final chapter, The Spiritual War on Reformed Theology by Dispensationalism, critiques the rise of Dispensationalism and its divergence from traditional Reformed theology, emphasizing the need for adherence to historic creeds and unified biblical interpretation to address modern theological disputes.

Harloff work calls for a return to foundational Christian doctrines to resolve contemporary issues within the church.
