The notion of law in the Bible seems to be code for karmic debt. "Whatever you do to others will be done to you". That's why people are repeatedly warned not to demand law, even in the Old Testament. Because it's impossible to be perfect, so you'll always rack up impossible amounts of debt, and keep doing so in the process of trying to pay off what you already have, and reincarnate forever. But by the same token if you don't demand justice, such graciousness will also be paid back to you, so there's a loophole. And perhaps with the help of a ransom.
