Romans is the definitive statement of Christian doctrine - the most comprehensive book in the New Testament. Its impact on history is unequaled. This is the first in a trilogy (Galatians, Hebrews) on Habakkuk 2:4 - "the just shall live by faith" - which later became the mantra of the reformation. It has an international outlook: As a Roman citizen, and with both Hebrew and Greek culture of history, religion, philosophy, poetry, science, music, etc., Paul's Epistle to the Romans is the most profound writing that exists anywhere. It is the definitive analysis on sin, the law, and grace, and it answers the most profound question: It may be that Deity can forgive sins, but I do not see how. (Socrates, 500 BC)
