What shall we say then? Is the law of Moses sinful? Certainly not! For I would not have known what sin was if it had not been for the law. For [example]; I would not have known [what it meant] to covet [i.e., have a strong desire for what belongs to someone else] except that the law said [Ex. 20:17], "You must not covet."

For He said to Moses [Ex. 33:19], "I will show pity to whomever I want, and I will show mercy to whomever I want."

For the Scripture said to Pharaoh [Ex. 9:16], "I raised you up [to be a ruler] for the very purpose of demonstrating my power in your life and that my name might be made known throughout the entire world."

Even as it is written [Ex. 28:16], "Look, I am placing a stone in the city of Zion that people will stumble over and a rock on which they will trip and fall. But the person who believes in Him will not be put to shame [i.e., he will never have unforgiven sin brought up against him]."

For [the commandments are: Ex. 20:13ff], "You must not be sexually unfaithful to your mate. You must not murder. You must not steal. You must not have a strong desire for what belongs to someone else." These and any other commandments are summed up in these words, "You must love your neighbor the same as you love yourself."
