Romans 2

As I mentioned yesterday, the reader should focus on the recipient (Jew or gentile converts) and take the writings in context to understand the intent of Paul.

In the first part of chapter 2 of Paul's writings to the Romans, it seems that he is writing more to the gentile converts.  Obviously, the gentile converts were not steep in Jewish law (law of Moses) or traditions.  But probably had lived amongst the false gods and wickedness of other Romans.  I believe that is why Paul focus's on the need to keep commandments for he summarized of man's agency and the natural man beginning with -

"....God gave them over to a reprobate mind, to do those things which are not convenient;
29 Being filled with all unrighteousness, fornication, wickedness, covetousness, maliciousness; full of envy, murder, debate, deceit, malignity; whisperers,
30 Backbiters, haters of God, despiteful, proud, boasters, inventors of evil things, disobedient to parents,
31 Without understanding, covenantbreakers, without natural affection, implacable, unmerciful:
32 Who knowing the judgment of God, that they which commit such things are worthy of death, not only do the same, but have pleasure in them that do them."  (New Testament | Romans 1:28 - 32)

Obviously, these gentile converts were to keep the commandments.  To them Paul continues -

"...thinkest thou this, O man, that judgest them which do such things, and doest the same, that thou shalt escape the judgment of God?
4 Or despisest thou the riches of his goodness and forbearance and longsuffering; not knowing that the goodness of God leadeth thee to repentance?
5 But after thy hardness and impenitent heart treasurest up unto thyself wrath against the day of wrath and revelation of the righteous judgment of God;
6 Who will render to every man according to his deeds..."  (New Testament | Romans 2:3 - 6)

Obviously, repentance and righteous deeds or obedience are conditions to receive His grace for -

"To them who by patient continuance in well doing seek for glory and honour and immortality, eternal life..."  (New Testament | Romans 2:7)

"But glory, honour, and peace, to every man that worketh good..."  (New Testament | Romans 2:10)

"(For not the hearers of the law are just before God, but the doers of the law shall be justified...."  (New Testament | Romans 2:13)

In the words to Roman gentile, it is my opinion that the "law" is the law that was given to them at their conversion, not the law of Moses being fulfilled by the Savior.
