Why is understanding the law's role important for Christians?

The law illustrates our sinfulness and incapacity to meet God's standards, driving us to seek the mercy found in Christ. By acknowledging that the law cannot justify us or sanctify us, Christians can appreciate the grace afforded to them through faith in Christ alone. Paul's teaching in Galatians emphasizes that we are not under the law but under grace, which allows us to see the law in a new light — not as a means of salvation, but as a tool that reveals our need for Christ and instructs us in godly living. This understanding helps believers grow in faith and assurance of their standing in Christ, migrating from a legalistic mindset to one of dependence upon grace.
