What does it mean? What does it matter?
Adam and Eve. God says, "Here is the law. Don't eat the fruit." And they were able to obey. Obviously, though, they didn't.
Israel. And God says again, "Here is the law." But this time it is utterly unfulfillable. Unattainable. Unreachable. Man has lost his one chance to not sin. So now he cannot stop sinning. So now the Law cannot merely be "don't eat" anymore. It's infinitely more complicated than that and the human condition is infinitely hopeless.
And so we are driven to search for hope. We are driven to God.
That's where Grace versus Works comes from. Our goodness, our works, are laughable in the face of so much required. And that's the point. Grace is the point. The condemnation must be taken away (or else we are dead). But the Law must be followed.
"When a willing victim who had committed no treachery was killed in a traitor's stead, the Table would crack and Death itself would start working backward." (C.S. Lewis, The Lion, the Witch, and the Wardrobe.)
The Law was not broken. The power of the Law was broken. The chains of the Law were broken. We are smothered, sheltered, washed, in righteousness. And through that death and sacrifice and rising again, through God's back turning, through wrath satisfied, we are clean. The Law has been kept for us. Law fulfilled. Redemption bought. We are free. And the Death turns into Life.
