17 But if you call yourself a Jew and depend upon the law and are proud of your relationship to God 18 and you know his will and approve the superior things because you receive instruction from the law, 19 and if you are convinced that you yourself are a guide to the blind, a light to those who are in darkness, 20 an educator of the stupid ones, a teacher of little children, because you have in the law the totality of knowledge and of the truth– 21 I ask you this: you who teach someone else, are you not teaching yourself? You who preach against stealing, do you steal? 22 You who are telling others not to commit adultery, do you commit adultery? You who abhor idols, do you rob temples? 23 You who are proud of your knowledge of the law dishonor God by transgressing the law! 24 Because just as it says in Scripture, “the name of God is being blasphemed among the Gentiles because of you.” 
the burden of light bearing
Paul had lived his life with the burden of being a law-light bearer. He knew how he had systematically brutalized and destroyed people all in the name of the truth of the law. So he knew the subtle way that law-keeping can turn the innocent into the guilty. So, he calls on the believing Jews in Rome to look within and realize that knowing the truth itself is not the answer. Good people need the gospel because our goodness itself can corrupt us and make us prideful. And pride produces all kinds of sin. The world sees the sin of believers and blasphemes God because of it. The gospel reduces us all to the status of sinner, and shows us all that salvation is available in Christ. That is the only freedom we have from the burden of light bearing.
LORD, thank you for the freedom you give us because of your atoning death. Thank you that we can walk in that freedom, and that our walk is not based on our obedience, but yours.
 Isaiah 52:5.
