The book of Romans
Introduction by Dr. Andy Woods (audio)
The book of Romans is the New Testament's longest, most structured, and most detailed description of Christian theology. Paul lays out the core of the gospel message: salvation by grace alone through faith alone. His intent is to explain the good news of Jesus Christ in accurate and clear terms. As part of this effort, Paul addresses the conflicts between law and grace, between Jews and Gentiles, and between sin and righteousness. As is common in his writing, Paul closes out his letter with a series of practical applications (BibleRef).
