This commentary is the fourth and final volume in Stewart Custer's series on New Testament genres. According to Custer, Paul's theological treatise to the Romans explores not only salvation but also foundational teachings such as sanctification, eschatology, and inspiration. With his characteristic love for solid biblical truth, Custer delves into the doctrines of Romans, providing background information, cross-references, sermon outlines, and practical application. The Righteousness of God also includes an exhaustive bibliography evaluating the other study resources available for the book of Romans.
