There is a liberal mantra that you cannot legislate morality. That is precisely what God did do at Sinai. What He did not do was force a heart change in the Israelite people. The Torah codified God's vision of a moral society. That vision has not wavered, Christ did not change it. Just like the Pharisees, the church today has drifted away from God's design as presented in the Torah. We can expect pretty much the same results.
