What is the purpose of the law according to the New Testament?

In the New Testament, particularly in Romans and Galatians, the law serves to reveal our sinful nature and our inability to achieve righteousness on our own (Galatians 3:24). It acts as a tutor, leading us to Christ so that we might be justified by faith. The law's primary role is diagnostic; it shows us our need for a Savior and underscores the grace we find in Christ, who fulfilled the law for us. By understanding the law's purpose in this light, believers are encouraged to rely fully on Christ's work rather than their flawed attempts to adhere to the law.
