The flight of the children of Israel from Mount Sinai indicates how people feel about the Law. They don’t like it. If this were the only argument to prove that salvation is not by the Law, this one Bible history would do the work. What kind of righteousness is this law-righteousness when at the commencement exercises of the Law Moses and the scrubbed people run away from it so fast that an iron mountain, the Red Sea even, could not have stopped them until they were back in Egypt once again? If they could not hear the Law, how could they ever hope to perform the Law? If all the world had stood at the mountain, all the world would have hated the Law and fled from it as the children of Israel did. The whole world is an enemy of the Law. How, then, can anyone be justified by the Law when everybody hates the Law and its divine author? All this goes to show how little the scholastics know about the Law. They do not consider its spiritual effect and purpose, which is not to justify or to pacify afflicted consciences, but to increase sin, to terrify the conscience, and to produce wrath. In their ignorance the papists spout about man’s good will and right judgment, and man’s capacity to perform the Law of God. Ask the people of Israel who were present at the presentation of the Law on Mount Sinai whether what the scholastics say is true. Ask David, who often complains in the Psalms that he was cast away from God and in hell, that he was frantic about his sin, and sick at the thought of the wrath and judgment of God. No, the Law does not justify. VERSE 20. Now a mediator is not a mediator of one. Here the Apostle briefly compares the two mediators: Moses and Christ. “A mediator,” says Paul, “is not a mediator of one.” He is necessarily a mediator of two: The offender and the offended. Moses was such a mediator between the Law and the people who were offended at the Law. They were offended at the Law because they did not understand its purpose. That was the veil which Moses put over his face. The people were also offended at the Law because they could not look at the bare face of Moses. It shone with the glory of God. When Moses addressed the people he had to cover his face with that veil of his. They could not listen to their mediator Moses without another mediator, the veil. The Law had to change its face and voice. In other words, the Law had to be made tolerable to the people.
