How do you explain Romans 2:12-15? It looks like Paul seems to believe that the key is behavior and that in many cases it comes from the peoples own nature.
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;
13:
(For not the hearers of the law are just before God, but the doers of the law shall be justified.14: For when the Gentiles, which have not the law,
do by nature the things contained in the law, these, having not the law, are a law unto themselves:
15: Which shew the work of the law written in their hearts, their conscience also bearing witness, and their thoughts the mean while accusing or else excusing one another
Again there is no mention here that the gentiles being discussed are moved by some external force, by the Spirit, or that they are Christians or have ever heard the Gospel. Infact it seems to be comparing most favorably the behavior of those outside the current community to those who are within.
