“Moreover the law entered, that the offense might abound.” Romans 5:20. In other words, “that sin by the commandment might become exceeding sinful.” Romans 7:13. It was given under circumstances of the most awful majesty, as a warning to the children of Israel that by their unbelief they were in danger of losing the promised inheritance. They did not, like Abraham, believe the Lord; and “whatsoever is not of faith is sin.” But the inheritance was promised “through the righteousness of faith,” and, therefore, the unbelieving Jews could not receive it. So the law was spoken to them, to convince them that they had not the righteousness that was necessary for the possession of the inheritance; for, although righteousness does not come by the law, it must be witnessed by the law. Romans 3:21. In short, the law was given to show them that they had not faith, and so were not true children of Abraham, and were therefore in a fair way to lose the inheritance. God would have put His law into their hearts, even as He put it into Abraham’s heart, if they had believed; but when they disbelieved, yet still professed to be heirs of the promise, it was necessary to show them in the most marked manner that their unbelief was sin. The law was spoken because of transgression, or, what is the same thing, because of the unbelief of the people. GTI 137.2
