How does the law relate to salvation according to Romans 4?

In Romans 4, Paul asserts that the law cannot justify or save; rather, it exposes human sinfulness. He states in Romans 4:15, 'Because the law worketh wrath: for where no law is, there is no transgression.' This verse highlights that the law reveals our need for grace rather than being a means to achieve righteousness. Paul explains that righteousness comes through faith, citing both Abraham and David as examples of individuals who were justified apart from the law's works. By emphasizing faith over the law, Paul illustrates how salvation is rooted in God’s promises fulfilled in Christ, reaffirming the Reformed understanding that salvation is entirely by grace through faith.
