[God saved us] without breaking the law of justice or canceling its demands. What He did in love was to satisfy its demands. The demands of justice were not ignored or canceled. They were fully satisfied. And the only way that God could do that was by having His spotless Son take the punishment that was due to us. What we see here is an amazing love. He did for us what we could not do for ourselves. We call this grace, the result of which is salvation.
