ASK DOC: WHAT IS THE PURPOSE OF THE LAW?

Ask Doc: If we are saved by grace alone, what is the purpose of the Law?

If salvation is by grace alone, what purpose does the Law serve?

This Ask Doc episode addresses one of the most misunderstood tensions in Scripture: the relationship between Law and grace. If the Law cannot justify, why did God give it—and what role does it still play?

Walking carefully through Galatians, Romans, and the broader biblical framework (KJV), this teaching clarifies that the Law was never designed to save, but to reveal sin, bring condemnation, and drive sinners to Christ. The Law exposes what man is; the gospel provides what man cannot produce.

This episode establishes:
Why the Law cannot justify any sinner
How the Law reveals and intensifies the knowledge of sin
The Law’s role as a “schoolmaster” leading to Christ
The difference between Law and promise in God’s redemptive plan
What it means to be no longer “under the Law, but under grace”
The Law is not the solution—it is the diagnosis. Christ is the cure.
Understanding this distinction protects the gospel from corruption and preserves the sufficiency of Christ’s finished work.

Scripture (KJV): Galatians 3:19–25; Romans 3:20; Romans 7:7; Romans 8:3–4; Ephesians 2:8–9
