The Book of Romans is considered by many to be the Crown on the Head of the New Testament, it is a book that starts in its first seven chapters to reveal the terrible state of the lost man, wether Gentile or Jew. And the Jewel in the Crown is chapter eight, where Paul finally gives the hope of salvation and the mentions the Holy Spirit for the first time, finally there is a way to God.
The central three chapters, nine to eleven, explain that God has not forgotton His people Israel and that He will keep His promises to them. The last chapters cover Christian Living, where Paul explains what being a Christian should entail.
The Book finally ends in the wonderful chapter sixteen, as Paul closes his Epistle by greeeting, commending, and expressing his love for a whole list of Christians in Rome (some of whom it is very suprising to hear of), and tells of Pheobe who, 'smuggled the glorious epistle to the Romans in the folds of her skirts'.
