Indeed you are called a Jew, and rest on the law, and make your boast in God, 18 and know His will, and approve the things that are excellent, being instructed out of the law, 19 and are confident that you yourself are a guide to the blind, a light to those who are in darkness, 20 an instructor of the foolish, a teacher of babes, having the form of knowledge and truth in the law. 21 You, therefore, who teach another, do you not teach yourself? You who preach that a man should not steal, do you steal? 22 You who say, “Do not commit adultery,” do you commit adultery? You who abhor idols, do you rob temples? 23 You who make your boast in the law, do you dishonor God through breaking the law? 24 For “the name of God is blasphemed among the Gentiles because of you,” as it is written. — Romans 2:17-24.
The sad thing is that the Jews think that because they have God’s law, they are accepted by Him. The truth is that because of their sinful insincerity, in both knowing and teaching God’s law while breaking it with blatant disregard, they will be judged. The Gentiles blaspheme God because of the insincerity and poor witness of the unbelieving and rebellious Jews, who, paradoxically, boast that they have God’s law. [Sourced from The Bible Panorama.]
