Romans 3:27

²⁷ Where is boasting then? It is excluded. By what law? Of works? No, but by the law of faith.

If we could be saved by works, we would have reason to boast. For by grace are ye saved through faith; and that not of yourselves: it is the gift of God: not of works, lest any man should boast (Ephesians 2:8-9).

Excluded = shut out, no room

Law (in this verse) = principle of procedure. By what sort of principle has boasting been excluded?

The law of faith = (The “the” should not be there.) Again, a principle. Justification is by the procedure of faith, not the procedure of works. And if by grace, then is it no more of works: otherwise grace is no more grace. But if it be of works, then is it no more grace: otherwise work is no more work (Romans 11:6).
