Grace Over Performance

Why We Are Justified by Faith, Not by Works

Galatians 2:11–21

Performance is something we, as human beings, have always valued. It is deeply woven into the way our world operates. From a young age, we learn that acceptance, recognition, and reward are often tied to how well we perform.

In his epistle to the Galatians, the Apostle Paul addresses this very issue. False teachers had started persuading the believers in Galatia that faith in Christ was not enough and that they also needed to keep the Jewish law in order to be justified by God.

To be justified means that God declares guilty sinners righteous in His sight, not because of anything they have done, but because of Christ’s righteousness credited to them through faith.

In Galatians 2:11–21, Paul even confronts the Apostle Peter for acting hypocritically by withdrawing from Gentile believers (non-Jewish Christians) out of fear of those who insisted on law-keeping.

Peter already knew the gospel. He had preached at Pentecost, where about 3,000 people were converted and added to the church (Acts 2:14–41). He had witnessed Gentiles receiving the Holy Spirit (Acts 10:44–48), later affirming that God had cleansed their hearts by faith (Acts 15:8–9), and he had defended their inclusion in God’s family (Acts 11:1–18). Yet his fear of the circumcision group caused him to act as though Gentile believers needed to adopt Jewish practices in order to enjoy full fellowship with God’s people.

Peter’s hypocrisy reminds us that even mature believers can act inconsistently with the gospel when fear of people begins to influence their conduct.

From this incident, Paul moves into one of Scripture’s clearest statements about justification: a person is justified through faith in Jesus Christ, not by works of the law (Gal. 2:16).

Our Natural Tendency Is to Earn God’s Acceptance

Throughout history, across cultures and religions, the natural tendency of the human heart has been to believe that divine favor can be earned through performance. People assume that by living moral lives, doing good deeds, making sacrifices, observing religious rituals, and trying their best, they can earn divine approval.

“Religion operates on the principle of ‘I obey—therefore I am accepted by God.’ The basic operating principle of the gospel is ‘I am accepted by God through the work of Jesus Christ—therefore I obey.'” —Tim Keller, The Prodigal God

Even if we did not grow up religious, starting with our parents, we learn from an early age that good behavior is often rewarded and bad behavior brings consequences. This is a healthy part of growing up, and even according to the Bible, our heavenly Father lovingly disciplines His children (Heb. 12:5–11) and graciously rewards those who seek and obey Him (Heb. 11:6; Matt. 6:4).

The danger comes when we confuse God’s fatherly discipline and reward with the basis of our acceptance before Him. We begin to believe that we must earn God’s love and acceptance through our performance. The gospel turns that way of thinking upside down.

Heart Check: When you’re reading your Bible consistently, praying faithfully, resisting temptation, and serving others, do you feel that God loves and accepts you more than when you’ve failed, neglected Him, or fallen into sin?

Through faith in Christ, we are graciously adopted into God’s family, and from the security of that relationship, we learn to obey. We do not keep Christ’s commands in order to become God’s children, but because we already are. God’s love, acceptance, and salvation are unconditional gifts that can only be received by faith.

When We Misunderstand Grace

In school, we receive grades based on our performance. Students earn scholarships because they excel academically or athletically. At work, promotions and raises are often given to those who perform well. Athletes are selected for teams, receive sponsorships, and are paid according to their performance. Even in everyday life, performance matters.

There is nothing inherently wrong with this. In fact, these systems often promote responsibility, diligence, and excellence. The problem arises when we begin to assume that God relates to us primarily in this way.

The Bible certainly calls us to obey God and pursue holiness (Gal. 5:16, 22–25; 1 Pet. 1:15–16; Heb. 12:14). Our love for Christ is expressed through obedience to His commands (John 14:15). Yet Galatians is equally clear that we cannot earn right standing with God through our performance. We are justified by faith in Christ, not by works of the law (Gal. 2:16).

In fact, even our growth in holiness is by God’s grace and empowerment. Paul asks the Galatians, “Having begun by the Spirit, are you now being perfected by the flesh?” (Gal. 3:3). We do not mature through self-reliant effort but by continuing to trust Christ and walk by the Spirit (Gal. 5:16).

Heart Check: Is your obedience motivated by gratitude for God’s grace and empowerment, or by fear of losing God’s acceptance?

Without understanding this, we can easily slip into believing that our right standing with God depends on how well we perform. The gospel reminds us that we are accepted because of Christ’s perfect performance, not our own. From that secure position of grace, we are then empowered to obey and grow in holiness.

“The law says, ‘Do this,’ and it is never done. Grace says, ‘Believe in this,’ and everything is already done.” — Martin Luther, Heidelberg Disputation, Thesis 26

The Galatian Problem Is Still Our Problem

The problem in Galatia was not with the Mosaic law itself, but with what the false teachers claimed lawkeeping could accomplish. They were convincing believers that faith in Christ was not enough. The law was holy and good, yet it was never given as a means by which sinners could earn justification before God.

The same principle applies to the laws of the land. Governments exist to restrain evil, promote justice, and protect society (Rom. 13:1–4). When we obey the law, we generally stay out of trouble. When we break it, there are consequences. Justice demands accountability.

Unlike civil law, which governs society, the Mosaic law was part of God’s covenant with Israel.

The Mosaic law was never given as a ladder by which sinners could climb their way into acceptance with God. Rather, it was given to expose sin, reveal God’s holy character, restrain evil, and ultimately point people to their need for the Savior. As Paul later explains, “the law was our guardian until Christ came, in order that we might be justified by faith” (Rom. 3:20, Gal. 3:24).

To be counted righteous before God, they argued, Gentile Christians also needed to keep the Jewish law, especially practices such as circumcision and other requirements of the Mosaic covenant (Gal. 2:3–5; 5:2–6).

This teaching appealed to a deeply rooted human instinct that is still with us today. We naturally assume God operates in the same way. Since He is the perfectly holy God, the giver of the Law, and the ultimate standard of righteousness, we conclude that if we perform well enough, do the things He commands, avoid the things He forbids, and live a good life, we will earn a right standing before Him.

But this is precisely where the gospel confronts our instincts. Paul insists that no one is justified by works of the law but only through faith in Jesus Christ (Gal. 2:16). Our right standing before God is not earned by our obedience; it is received by grace through faith. From that secure standing, we are then empowered by the Holy Spirit to live lives of joyful obedience.

A Holy God and a Sinful Humanity

Performance becomes problematic when we have a skewed view of both God and humanity.

Scripture tells us that God is perfectly holy, righteous, just, incorruptible, all-wise, all-powerful, and utterly magnificent. He is completely set apart from His creation. There is no one like Him. As Isaiah declared, “Holy, holy, holy is the Lord Almighty” (Isaiah 6:3). God is so pure that “His eyes are too pure to look on evil” (Habakkuk 1:13), and He dwells in “unapproachable light” (1 Timothy 6:16).

Now compare that to humanity.

The Bible does not describe us as basically good people who simply need to try a little harder. Rather, it tells us that although we are fearfully and wonderfully made in God’s image (Gen. 1:26–27; Ps. 139:14), we are also deeply broken by sin, lawbreakers at our core (1 John 3:4), and spiritually dead apart from Christ (Eph. 2:1–3).

As Paul explains, “the Scripture imprisoned everything under sin” (Gal. 3:22), and “all have sinned and fall short of the glory of God” (Rom. 3:23). Apart from Christ, our sin leaves us alienated from God and unable to reconcile ourselves to Him (Rom. 5:10; Isa. 59:2).

We are like a person drowning in the middle of a vast, storm-tossed ocean with no land in sight. We cannot save ourselves. Our only hope is for a rescuer to come. Christ has come to rescue us, and we receive that rescue not by our own efforts, but by placing our faith in Him.

That is why no amount of moral performance, religious activity, or good works can reconcile us to a perfectly holy God. If acceptance before God depended on our performance, every one of us would fail, because every one of us has already failed.

Christ’s Perfect Performance, Not Ours

This is exactly why the gospel is such good news.

Because we could never earn His favor, God did for us what we could never do for ourselves. Jesus Christ lived the perfect life we failed to live, fulfilled the Law completely, and willingly died on the cross to bear the punishment our sins deserved. On the third day, He rose again, demonstrating His victory over sin and death and vindicating His saving work.

This is the heart of Paul’s message:

“A person is not justified by the works of the law, but by faith in Jesus Christ.” – Galatians 2:16

Our relationship with God rests not on what we have done for Him, but on what Christ has done for us. We don’t work to earn His favor; we live from the grace we have already received through faith in Jesus Christ.

Because Christ has justified us by grace through faith, we no longer have to live under the crushing burden of trying to earn God’s favor. As Paul declares, “It is for freedom that Christ has set us free. Stand firm, then, and do not let yourselves be burdened again by a yoke of slavery” (Gal. 5:1).

“Your worst days are never so bad that you are beyond the reach of God’s grace, and your best days are never so good that you are beyond the need of God’s grace.” — Jerry Bridges, The Discipline of Grace

As Paul concludes this section, he leaves us with this sobering reminder: “I do not set aside the grace of God, for if righteousness could be gained through the law, Christ died for nothing!” (Gal. 2:21).

Instead of striving to earn God’s acceptance, the Christian life begins with a new identity. We have died with Christ, and now Christ lives in us. Our obedience is no longer an attempt to earn God’s acceptance but the fruit of already belonging to Him.

Therefore, Paul writes:

“I have been crucified with Christ and I no longer live, but Christ lives in me. The life I now live in the body, I live by faith in the Son of God, who loved me and gave himself for me.” (Gal. 2:20)
