Romans 2:17-20

What about you? You call yourself a Jew. You trust in the law of Moses and brag that you are close to God. You know what he wants you to do and what is important, because you have learned the law. You think you are a guide for the blind and a light for those who are in darkness. You think you can show foolish people what is right and teach those who know nothing. You have the law; so you think you know everything and have all truth.
