Relying on the Law
17 Now you, if you call yourself a Jew; if you rely on the law and boast in God; 18 if you know his will and approve of what is superior because you are instructed by the law; 19 if you are convinced that you are a guide for the blind, a light for those who are in the dark, 20 an instructor of the foolish, a teacher of little children, because you have in the law the embodiment of knowledge and truth— 21 you, then, who teach others, do you not teach yourself? You who preach against stealing, do you steal?22 You who say that people should not commit adultery, do you commit adultery? You who abhor idols, do you rob temples? 23 You who boast in the law, do you dishonor God by breaking the law? 24 As it is written: “God’s name is blasphemed among the Gentiles because of you.”
I trust my mechanic and when I feel that there is a problem with my vehicle, I will take it to him and he will let me know whether something needs to be done or not. It would not make sense to go to somebody who wasn’t trained in their field and ask them for guidance and feedback. I may have had a bad mechanic in the past and I just simply move on and find another.
The Jews were to receive the inheritance and were chosen by God. They were instructed by the law and were the experts, knowing all the rules and laws that the people should follow. However, being a teacher and doing something different is hypocritical. With pride, they can feel that they are above the law. Paul reminds them that the Jews are no more superior than the Gentiles when it comes to the saving grace of Jesus. Jesus died for everybody, no matter what socio-economic level they are at.
