Q. How do you understand the relationship between the law and grace?
A. Simply put they are opposites. The Law tells us we can’t become righteous no matter what we do. We can only discover our need for a Savior.
Therefore no one will be declared righteous in his sight by observing the law; rather, through the law we become conscious of sin. (Romans 3:20).
Grace tells us we can become righteous, but only by believing we have a Savior who has made us so.
But now a righteousness from God, apart from law, has been made known, to which the Law and the Prophets testify. This righteousness from God comes through faith in Jesus Christ to all who believe. (Romans 3:21-22)
