Why is understanding the purpose of the Law important for Christians?

The importance of understanding the Law lies in its role in highlighting human sinfulness and the necessity of faith in Christ for salvation. As Martin Luther noted, the Law exposes our guilt, pointing us away from self-reliance and towards reliance on God's provision in Christ (Galatians 3:19). This insight allows Christians to properly appreciate the Gospel, experiencing the transformative power of grace that liberates from the condemnation of the Law. Consequently, believers can grow in their relationship with Christ and express their faith through love rather than fear of the Law.
