Can the law save anyone?
No, the law cannot save anyone. The law has no mercy and can do nothing but condemn. Its only function is to condemn, not to save. It cannot provide salvation; it demands perfect obedience and brings condemnation.
Les explains that the law, which is under the mercy seat, is the demanding law. He emphasizes that there is no mercy in the law and that the law can do nothing. The only thing the law can do is condemn you. The law can't save anybody. All the law can do is condemn. This is contrasted with the sin offering and burnt offering that Aaron was instructed to bring, showing that salvation requires sacrifice, not law-keeping.
