We ought never to forget when reading our Bibles that the chapter headings and the verses are not of inspired origin, but were placed there to make studying and locating passages more convenient.  Very often we have a new chapter in our Bibles, but not a new context.  I say this because it is important that we do not read Romans chapter 5 as if it were somehow disjointed from chapter 4.  The very word with which Paul begins this chapter, therefore, shows that he is drawing a conclusion from his previous argument regarding the imputation of righteousness to those who believe on Him that raised up Jesus our Lord from the dead.

So then, we ought to reflect momentarily upon what has gone before.  Paul has gone through great pains to prove that no man is justified by his keeping of the law, but by faith in Christ alone, Whose blood takes away our sins, and Whose righteousness is imputed to us for our acceptance before God.  To utterly disarm the Jews of their best argument, he showed that even Abraham and David, two of the greatest stalwarts in the history of God’s people, received salvation by grace through faith.  He then concluded that we enter into salvation through the same method.  God, because of Christ, refuses to charge us with our sins, but instead, when we trust His promises, imputes righteousness to us, even as He did to Abraham.  The person who has the righteousness of God charged to his record before God, cannot but be saved, and be secure in that salvation he has obtained.  This will be the apostle’s great theme through the first 11 verses of this chapter, and he will touch upon it again at various points all the way through chapter 8.
