I like your reasoning on this point. In addition and biblically speaking, Yahweh would not give a law that would contradict his creation. Mosaic Law and other laws have great similarities because mankind is created in the image of God. Although marred in every area, mankind (whether Jew or Gentile) retains vestige of righteousness and holiness. Yahweh did not create and give the Hebrews something new to the universe nor did he create something specifically for the nature of the Hebrews, but codified what was already his law in the lives of every person. To my understanding, giving the Law to Moses to give to the Children of Israel is something that carries over from Old Testament to New: God’s people are to be peculiar, not like the rest of the nations, for the purpose of being a light in a dark world. In relation to Israel, it was more than just a rule book, but they were not able to keep it fully if they were meant to be just robots. The Mosaic Law, as well as all other codes, show the need for the grace of God. A person can never fully live up to the law of God, nor to the law that he creates in his own life or country.

Thanks again.
