We've been enjoying a "consecutive reading" of Romans during morning worship and when this passage was read, I couldn't stop hearing the italicized passage. I know this - you know this - but Paul surrounds it with such a logical building that it took on new significance and took my breath away.
But if you call yourself a Jew and rely on the law and boast in God and know his will and approve what is excellent, because you are instructed from the law; and if you are sure that you yourself are a guide to the blind, a light to those who are in darkness, an instructor of the foolish, a teacher of children, having in the law the embodiment of knowledge and truth—you then who teach others, do you not teach yourself? While you preach against stealing, do you steal? You who say that one must not commit adultery, do you commit adultery? You who abhor idols, do you rob temples? You who boast in the law dishonor God by breaking the law. For, as it is written, “The name of God is blasphemed among the Gentiles because of you.” (Romans 2:17-24 ESV, italics mine)
