In Romans 2 Paul shows that the SAVED saints are to be found among both the Jews and the Gentiles and the stubborn lost are to be found BOTH among the Jews and the Gentiles.
He has spent chapter 1 contrasting the lost world to the saved saints of the world world.
He spent chapter 2 contrasting the lost among Jews and Gentiles to the saved among Jews and Gentiles.
Thus he did away in Chapter 2 with the notion "you are saved because you are a Jew and you are lost because you are a gentile". Paul points out that there are lost among BOTH and there are saved among BOTH groups.
Rom 2
7 to those who by perseverance in doing good seek for glory and honor and immortality, eternal life;
8 but to those who are selfishly ambitious and do not obey the truth, but obey unrighteousness, wrath and indignation.
9 There will be tribulation and distress for every soul of man who does evil, of the Jew first and also of the Greek,
10 but glory and honor and peace to everyone who does good, to the Jew first and also to the Greek.
11 For there is no partiality with God.
12 For all who have sinned without the Law will also perish without the Law, and all who have sinned under the Law will be judged by the Law;
13 for it is not the hearers of the Law who are just before God, but the doers of the Law will be justified.
14 For when Gentiles who do not have the Law do instinctively the things of the Law, these, not having the Law, are a law to themselves,
15 in that they show the work of the Law written in their hearts, their conscience bearing witness and their thoughts alternately accusing or else defending them,
16 on the day when, according to my gospel, God will judge the secrets of men through Christ Jesus.
26 Therefore if the uncircumcision keep the righteousness of the law, shall not his uncircumcision be counted for circumcision?
27 And shall not uncircumcision which is by nature, if it fulfil the law, judge thee, who by the letter and circumcision dost transgress the law?
28 For he is not a Jew, which is one outwardly; neither is that circumcision, which is outward in the flesh:
29 But he is a Jew, which is one inwardly; and circumcision is that of the heart, in the spirit, and not in the letter; whose praise is not of men, but of God.
14 For when Gentiles who do not have the Law do instinctively the things of the Law, these, not having the Law, are a law to themselves,
15 in that they show the work of the Law written in their hearts,
The New Birth promise of Heb 8 "The Law written on the heart" is being identified in that Romans 2 section above. Impossible to miss for the unbiased objective Bible student.
In Romans 2 Paul does NOT argue "all Jews are lost" rather he argues that every man among the Jews and the Gentiles (BOTH groups) will go to heaven if the fruits show the born-again New Covenant result of a good tree, and every man among BOTH Jews and gentiles that shows the result of bad fruit will be found to be a bad tree - and will in the end - to to hell based on an unbiased impartial law regarding the fruit of the good tree vs the bad tree.
A principle Christ himself identifies in Matt 7.
Paul says that this is IN the context of the Gospel call to repentance and the Gospel good news of the future judgment where as Daniel notes "Judgement is passed in favor of the saints".
It just does not get any easier than this!
=========
Thus in Romans 3 it is logical to ask "Well then what ADVANTAGE is there to being a Jew" if in fact there are SAVED among BOTH Jew AND Gentile just as there are the lost among BOTH Jew AND Gentile.
so in Romans 3 Paul says that advantage is in "Scripture" - the Jews are those who have the blessing of access to scripture where can be found - the Gospel.
in Christ,
