The Truth About Good Works: Can They Justify Us Before God?

The Nature of Justification: A Gift of Grace

To understand whether good works can justify a person before God, we must first define what justification means. Justification is the act by which God declares a sinner to be righteous, not because of anything they have done, but solely based on the righteousness of Jesus Christ. This righteousness is imputed to us through faith in Jesus, and it is entirely a gift of God’s grace. Justification is not something we can earn; it is given freely because of what Christ has done for us.

In Ephesians 2:8-9, Paul writes, “For by grace you have been saved through faith, and that not of yourselves; it is the gift of God, not of works, lest anyone should boast.” This passage makes it clear that justification is by grace alone through faith. It is not of ourselves, and it is not the result of our works. If justification could be earned through good works, then grace would no longer be grace, and we would have reason to boast in our own righteousness. But God, in His wisdom, has designed salvation in such a way that no one can take credit for it. It is entirely His doing.

Grace, therefore, excludes the possibility that good works can justify us before God. Our works, no matter how good, cannot erase the guilt of our sin or make us right before a holy God. Justification is a divine act of God’s grace, completely independent of our efforts or merits.

The Inability of Good Works to Erase Sin

One of the reasons good works cannot justify a person before God is that they cannot erase the guilt of sin. Every person is born into sin and is guilty before God. The Bible teaches that even our best efforts are tainted by sin and fall far short of God’s perfect standard of righteousness. No amount of good works can cover up or remove the stain of sin.

Isaiah 64:6 gives a sobering picture of the futility of good works: “But we are all like an unclean thing, and all our righteousnesses are like filthy rags; we all fade as a leaf, and our iniquities, like the wind, have taken us away.” Even the good deeds we do are, in comparison to God’s perfect holiness, like filthy rags. This shows that no matter how many good works we accumulate, they cannot make us acceptable in God’s sight.

The problem of sin is so deep and pervasive that it requires more than good works to fix. It requires a perfect sacrifice—one that can fully atone for our sin and satisfy God’s justice. That is why God sent His Son, Jesus, to die on the cross. Only the blood of Jesus can cleanse us from sin and make us righteous before God. Hebrews 9:22 explains this truth: “And according to the law almost all things are purified with blood, and without shedding of blood there is no remission.” Good works cannot remove the penalty of sin; only the death of Jesus can do that.

Justification by Faith, Not Works

The Bible teaches that we are justified by faith, not by works. This is a central truth of the gospel and is repeated throughout the New Testament. Faith is the means by which we receive the righteousness of Christ. It is not that faith itself justifies us, but that through faith, we are united with Christ, and His righteousness is credited to us. This is what allows us to stand justified before God—not our works, but His work.

In Romans 3:28, Paul declares, “Therefore we conclude that a man is justified by faith apart from the deeds of the law.” This passage makes it clear that no amount of law-keeping or good works can justify a person. Justification is by faith alone, apart from works. This does not mean that good works are unimportant, but it does mean that they play no role in our justification. We are made right with God by trusting in what Jesus has done, not in what we have done.

Paul also makes this point in Galatians 2:16: “Knowing that a man is not justified by the works of the law but by faith in Jesus Christ, even we have believed in Christ Jesus, that we might be justified by faith in Christ and not by the works of the law; for by the works of the law no flesh shall be justified.” Again, we see that justification comes through faith in Jesus, not through works of the law. Our efforts to follow the law or to do good works cannot earn us a right standing before God. Only faith in Christ can justify us.

The Role of Good Works After Justification

While good works cannot justify us, they do play an important role in the Christian life after we have been justified. Good works are the fruit of our faith; they are the evidence that we have been truly justified by grace through faith. When we are justified, we are given a new heart and a new nature, and as a result, we begin to live in a way that reflects God’s character. Good works are the natural outflow of a life transformed by the grace of God.

James 2:17 speaks to the necessity of good works as a demonstration of faith: “Thus also faith by itself, if it does not have works, is dead.” James is not contradicting Paul’s teaching that we are justified by faith alone. Instead, he is saying that true, saving faith will always result in good works. Faith that does not produce good works is not genuine faith. Good works are the fruit that shows the reality of our justification, but they are not the root of it.

Ephesians 2:10 explains the relationship between good works and justification beautifully: “For we are His workmanship, created in Christ Jesus for good works, which God prepared beforehand that we should walk in them.” After we are justified, we are called to live out the good works that God has prepared for us. These works are not the basis of our justification, but they are the result of it. We are saved by grace through faith, and we are saved for the purpose of doing good works that glorify God.

The Dangers of Relying on Good Works for Justification

Relying on good works for justification is a dangerous and futile pursuit. When we try to justify ourselves by our works, we are essentially saying that Christ’s sacrifice on the cross was not enough. We are placing our confidence in ourselves rather than in the finished work of Jesus. This not only leads to self-righteousness but also undermines the gospel of grace.

Galatians 5:4 warns against this: “You have become estranged from Christ, you who attempt to be justified by law; you have fallen from grace.” When we rely on good works or law-keeping to justify us, we alienate ourselves from the grace of God. Justification by works and justification by grace are mutually exclusive. We cannot earn God’s favor through our works; we can only receive it as a gift of His grace.

Relying on good works for justification also leads to a lack of assurance. If we believe that our standing before God depends on our performance, we will never know if we have done enough to be accepted by Him. This leads to fear, uncertainty, and ultimately despair. But when we trust in Christ alone for our justification, we have full assurance that we are accepted by God, not because of what we have done, but because of what Christ has done. Romans 5:1 offers this assurance: “Therefore, having been justified by faith, we have peace with God through our Lord Jesus Christ.” Faith in Christ brings peace and confidence, while reliance on works brings anxiety and doubt.

Conclusion: Trusting in Christ, Not in Works

Good works, while important in the life of a believer, can never justify a person before God. The Bible makes it clear that justification is a gift of God’s grace, received through faith in Jesus Christ. Our works, no matter how good, cannot remove the guilt of our sin or earn us favor with God. Only the death and resurrection of Jesus can do that.

Relying on good works for justification not only leads to self-righteousness but also rejects the grace of God. True justification comes only through trusting in the finished work of Christ, and it results in a life that produces good works as the fruit of that faith. As believers, we are called to live lives of obedience and good works, but we must never trust in those works for our justification. Our hope and confidence must always rest in Jesus, the One who justifies us by His grace alone.
