Certainly not. And since I know how important italics, caps and the like are, I have taken my liberties with the formatting of the text as follows:
Romans2:14 Indeed, when Gentiles, who do not have the law, do BY NATURE things required by the law, they are a law for themselves, even though they do not have the law, 15 since they show that the requirements of the law are written on their hearts, THEIR CONSCIENCES ALSO BEARING WITNESS, and their thoughts NOW accusing, NoW eVeN defending them.
This does not say that unregenerate man can come to Christ without being regenerated . This is a teaching of Paul that we all need a Savior, that all men know the law (without the law there is no sin) from the tablets or the heart . . They know when they "sin" as their conscience tells them and accuses them . They are ruled as guilty and as much in need of a Savior as the Jews.
Rom 2:11 For there is no respect of persons with God.
Rom 2:12 For as many as have sinned without law shall also perish without law: and as many as have sinned in the law shall be judged by the law;
Paul sums up the need for a Savior in the next chapter
Rom 3:9 What then? are we better [than they]? No, in no wise: for we have before proved both Jews and Gentiles, that they are all under sin;
Rom 3:10 As it is written, There is none righteous, no, not one:
Rom 3:11 There is none that understandeth, there is none that seeketh after God.
Rom 3:12 They are all gone out of the way, they are together become unprofitable; there is none that doeth good, no, not one.
The clear doctrine that Paul is attempting to teach is man needs a Saviour . He goes on to teach we can not find that Savior ourselves. We do not understand the scriptures nor do we seek God . We have all gone out of our way
