The book of Romans is a Pauline Epistle (letter from Paul). The Apostle Paul wrote it roughly about 56-57 A.D. The key personalities in the book of Romans are the Apostle Paul, and Phoebe who delivered this letter. Paul wrote the letter to the believers in Rome, hence the name "Romans". He wrote it to give them a concrete theological foundation on which to construct their faith and to live for and serve God effectively. The book of Romans reveals the answers to important questions and supplies information on many topics, such as salvation, the sovereignty of God, judgment, spiritual growth, and the righteousness of God. Many scholars also describe it as The Gospel and the Righteousness of God, which can be received only by faith in the atoning death of Jesus Christ. The focus of the "righteousness of God" is foundational throughout the book of Romans. In fact, it is threaded through every section of the basic outline of this epistle. Paul reiterates this so that the reader may realize that salvation cannot be attained through man's good deeds but only through faith in God's righteousness: "I am not ashamed of the gospel, because it is the power of God for the salvation of everyone who believes... For in the gospel a righteousness from God is revealed, a righteousness that is by faith" (1:16-17). You cannot repair your relationship with God through your good deeds; this is only accomplished through faith in the perfect and finished work of Jesus Christ.
