Many believers struggle with the purpose of the law in Scripture. If salvation comes through Christ, why did God give the law at all? Why did the law come after the promise, and why does the Bible emphasize that no one can be saved by it?
To answer these questions, we must understand the relationship between the promise, the law, and Christ.
The Promise Came Before the Law
God gave the promise of the Messiah to Abraham long before the law ever existed. Scripture tells us that the law was introduced about 400 years after the promise was made (Galatians 3:17). This timing is important.
The law did not cancel the promise, not because it came later, but because it was born out of the promise itself. The promise revealed God’s intention to redeem mankind through Christ, while the law was given to prepare humanity for the fulfillment of that promise.
In other words, the law was never meant to replace the promise – it was meant to serve it.
The Law as Preparation, Not Salvation
The law was given to prepare man for the coming of Christ. It revealed God’s standard of righteousness and exposed the fallen nature of humanity. The righteousness God requires cannot be fulfilled by human effort alone, because the fallen flesh cannot accommodate the work of the Spirit.
This is why the crucifixion of the flesh is essential. Until man recognizes the inability of the flesh to meet God’s righteous demands, true transformation cannot occur. The law highlights this inability.
Why Obedience Was Emphasized
The law subjected man to obedience in order to restrain transgression until Christ came. As Scripture explains:
“Wherefore the law was our schoolmaster to bring us unto Christ, that we might be justified by faith.”
— Galatians 3:24 (KJV)
Through the law, man became aware of sin. Obedience was demanded not to make man righteous, but to reveal how deeply unrighteous he truly was without divine help.
The law restrained sin externally, but it could not change the heart internally. That change would only come through Christ, in whom man is crucified and given the enablement to live in obedience by the Spirit.
Salvation Is Not Found in the Law
One of the clearest truths of Scripture is that salvation is not in or by the law. The law cannot save because it was never designed to do so. Instead, it was given to force man to a point of honest self-awareness.
By attempting to keep the law and failing repeatedly, man comes face to face with his weakness and helplessness. This failure produces a hunger – not for stricter rules – but for a Savior.
Was the Law Meant to Be Broken?
In a very real sense, yes.
The law was purposefully given to be broken, not because God desired sin, but because breaking the law reveals the impossibility of self-righteousness. It is in failing to keep the law that man discovers his need for grace.
As man breaks the law, the law fulfills its purpose.
“For by the law is the knowledge of sin.” — Romans 3:20 (KJV)
Without the law, man would never fully understand the depth of his fallen condition or his need for redemption.
The Law Leads Us to Christ
Ultimately, the law serves as a guide, pointing us toward Christ. It exposes weakness, reveals sin, and strips man of pride. Once man realizes he cannot save himself, he becomes ready to receive the Savior.
Christ fulfills what the law could only demand. In Him, the flesh is crucified, the Spirit is given, and obedience becomes possible – not by force, but by transformation.
Conclusion: The Law Had a Divine Purpose
The law was not a mistake. It was not God changing His mind. It was a strategic step in God’s redemptive plan.
- The promise revealed God’s intention
- The law exposed man’s condition
- Christ fulfilled both
The law leads us to Christ, and once we arrive, we no longer live under condemnation but under grace. Understanding this truth brings clarity, freedom, and deeper appreciation for the work of Christ.
