I understand Romans 2,3
But you need to understand this
Romans 9:30. What shall we say then? That the Gentiles, which followed not after righteousness, have attained to righteousness, even the righteousness which is of faith.31. But Israel, which followed after the law of righteousness, hath not attained to the law of righteousness.32. Wherefore? Because they sought it not by faith, but as it were by the works of the law. For they stumbled at that stumblingstone;”
My theology is so far very sound It has not been corrected in here yet. Stick with Paul’s words from Galatians and other parts about the law and hopefully it will be seen what he is really talking about
Also consider this
2 Corinthians 3:6. Who also hath made us able ministers of the new testament; not of the letter, but of the spirit: for the letter killeth, but the spirit giveth life.7. But if the ministration of death, written and engraven in stones, was glorious, so that the children of Israel could not stedfastly behold the face of Moses for the glory of his countenance; which glory was to be done away:8. How shall not the ministration of the spirit be rather glorious?9. For if the ministration of condemnation be glory, much more doth the ministration of righteousness exceed in glory.10. For even that which was made glorious had no glory in this respect, by reason of the glory that excelleth.11. For if that which is done away was glorious, much more that which remaineth is glorious.12. Seeing then that we have such hope, we use great plainness of speech:13. And not as Moses, which put a vail over his face, that the children of Israel could not stedfastly look to the end of that which is abolished:14. But their minds were blinded: for until this day remaineth the same vail untaken away in the reading of the old testament; which vail is done away in Christ.15. But even unto this day, when Moses is read, the vail is upon their heart.”
