How should believers view the Old Testament law?

In Reformed theology, the Old Testament law serves a purpose in revealing God's holiness and human sinfulness but is not the rule of life for believers. As Paul states, being led by the Spirit means Christians are free from the law (Galatians 5:18). The law cannot justify or sanctify; rather, it highlights the need for grace, for it is through faith in Christ that believers are made righteous. The law as a rule of life can become a burden that distracts from the grace and peace found in Christ, leading to confusion about the true nature of righteousness.
