"What then? Are we Jews any better off? No, not at all. For we have already charged that all, both Jews and Greeks, are under sin (Romans 3:9)." This is pretty much telling us that everyone including the Jews are under sin. No one is better off. Well you may ask what about Romans 3:1-2? Yes the Jews have an advantage over the gentiles, they were given the oracles of God. So they know the law but yet still are unfaithful to it. So the Jews have an advantage over the Gentiles but are not better off because they all are under sin.
" None is righteous, no not one; no one understands; no one seeks for God. All have turned aside; together they have become worthless; no one does good, not even one (Romans 3:10-12)." Once again Paul emphasizes that we are all under sin. Paul also says something very interesting, no one seeks for God. What does this mean? It means that no one on his own seeks for God. Now what is this part about no one does good? What about that time I helped that old lady across the street or when that guy dropped his wallet and I gave it back to him instead of taking it? Are those not good deeds? The issue Paul is addressing here is that prior to salvation people do perform actions that resemble goodness, but these actions are still stained by evil, since they are not done for Gods glory and do not come from faith.
