I can't begin to count the times I have heard or been in conversations about the Law. That's the Law of Moses, as in the Ten Commandments - and a lot more.
Some say the Law is no longer valid. But then others respond, "So, you mean it's okay to murder, steal and chase your neighbor's wife?" Well, no, comes the reply. Of course not.
Others say the Law is still in effect, and we are obligated to keep it. But then some respond, "So, you mean we're supposed go to Jerusalem to offer sacrifices?" Well, no, is the reply. Of course not.
