147. Why the Law Could Not Save Us

The Law of Moses was perfect because it came from a perfect God. Yet Scripture teaches that the Law could not save humanity. The problem was never the Law itself but the condition of the human heart. Paul writes, "The law is holy, and the commandment is holy and righteous and good" (Romans 7:12). At the same time, "through the law comes knowledge of sin" (Romans 3:20).
God's commandments reveal His holiness. The Law shows what righteousness looks like, but it does not give fallen humanity the power to become righteous. Humanity inherited from Adam a wounded nature marked by mortality and an inclination toward sin. As a result, every person falls short of God's glory.
This explains why even sincere religious effort cannot restore us to God.
Throughout history people have tried to make themselves acceptable through sacrifices, religious rituals, moral living, charitable works, pilgrimages, fasting, traditions or strict observance of religious laws. While many of these practices are good when done with faith and humility, none of them can remove sin or reconcile humanity to God apart from His grace.
Even the sacrifices of the Old Covenant could only provide a temporary covering of sins. They pointed forward to Christ but could never permanently cleanse the conscience. Likewise, external obedience to the Law could restrain outward behavior, but it could not remove pride, anger, lust, selfishness or unbelief from the heart.
The seriousness of sin is often underestimated. A single act of rebellion against a perfectly holy God disrupts communion with Him. Humanity measures sin against other sinners, but God measures it against His own perfect holiness. This is why no amount of good works can erase sin. A person may perform countless acts of kindness and yet still remain separated from God because the deeper problem lies within the heart itself.
The Law therefore teaches several vital truths:
  • God is perfectly holy.
  • Every human being is a sinner living in a fallen condition.
  • Sin separates humanity from communion with God.
  • Human effort alone cannot restore that communion.
  • Good works, religious observances, sacrifices and external rituals cannot save.
  • The Law itself cannot heal the human heart.
Recognizing these truths is not meant to produce despair but humility. Once we understand our condition, we stop blaming only the evil around us and recognize that we ourselves contribute to the brokenness of the world. We discover that our own strength is insufficient. Our flesh cannot save us. The Law cannot save us. Religion alone cannot save us. Even our best works cannot bridge the infinite distance between sinful humanity and the holy God.
This is the bad news of the Gospel. Left to ourselves, we cannot save ourselves.
Like Paul, we are compelled to cry out:
"Wretched man that I am! Who will deliver me from this body of death?" (Romans 7:24)
That question prepares us for the greatest news ever proclaimed. The answer is not found in ourselves, nor in the Law, but in Jesus Christ, who fulfilled the Law, conquered sin and death and established the New Covenant through His grace.
"Thanks be to God through Jesus Christ our Lord!" (Romans 7:25)
