Justified by Faith: Living in Grace, Not Law

Paul brings up a proper bit of drama in Galatians 2. Peter had been eating with Gentile Christians, sharing the table like God had already told him to do, and then some men from James arrived. Peter pulled back. Peter ditched one group for another group, like a high school cafeteria moment, an “on Wednesdays, we wear pink” situation. Paul sees that this is not just rude or awkward. Paul sees that Peter is not acting in line with the truth of the gospel.

God had already shown Peter in Acts 10 that the old clean and unclean boundaries were done. The sheet came down, the animals were there, and God’s voice said, “Do not call anything impure that God has made clean.” Peter then went to Cornelius, entered a Gentile house, preached Jesus, and watched Gentiles receive salvation. Peter knew the deal. God had made it clear that Gentiles were not second-class members of the family.

Peter’s withdrawal says something without words. Peter’s action says, “There is a difference between us Jews and those Gentiles.” That is the problem. God has said there is no difference anymore. The grace of God through Jesus is for any and every person who comes to him, regardless of race, status, family, talent, charisma, wealth, or anything else.

Paul therefore reminds Peter who he is. Peter has forgotten the basic principle: a person is not justified by works of the law, but by faith in Jesus Christ. Justification is courtroom language. God the judge gives the verdict of acquittal. That does not mean innocence, because sinners really have sinned. It means those who have Jesus as their lawyer, those who trust him as Lord and Saviour, are released from accusation and freed from obligation regarding the charges. It is “just if I’d never sinned.”

Grace frees Peter from needing approval from the circumcision group. Peter already has Christ’s approval, so the opinions of those men do not need to control him. People-pleasing can shut others out of God’s family, but the gospel opens the table to a Revelation 7 multitude from every nation, tribe, people, and language.

Paul also exposes the danger of hedging bets. Religious service, giving, and good works are wonderful ways to serve Jesus, but they cannot seal the deal with God. Christ’s death and resurrection are the once-for-all silver bullet to sin and death. Nothing needs to be added. If righteousness could be gained through the law, Christ died for nothing.

Key Takeaways

• 1. Grace makes one table [32:32] Peter’s withdrawal preached a false gospel without needing to say a word. Grace does not allow one group to sit as if cleaner, safer, or more acceptable than another. Christ has made a family where old boundary markers no longer have the final say. [32:32]
• 2. Justification is acquittal, not innocence [36:54] The gospel does not pretend that sin never happened. Justification means God gives a real verdict over guilty people because Christ stands for them. That distinction protects both honesty about sin and deep comfort in grace. [36:54]
• 3. Christ’s approval frees fearful hearts [42:24] Peter’s fear of the circumcision group shows how quickly approval can become a master. Grace reminds the believer that Christ’s verdict is already enough. When that verdict lands properly, the shifting opinions of people lose their power to rule. [42:24]
• 4. Good works cannot seal salvation [45:56] Service can become a quiet attempt to hedge bets with God. The gospel reframes obedience as gratitude, not payment. Christ’s death and resurrection need no top-up, no backup plan, and no extra insurance. [45:56]
• 5. Grace must be lived out now [49:19] Paul’s question presses grace into ordinary situations: what does living out and enjoying God’s grace look like here? Grace is not only a doctrine to defend, but a reality to keep in step with. The believer lives Christ’s life now, not a life of earning.

Bible Reading

Galatians 2:11-21
But when Cephas came to Antioch, I opposed him to his face, because he stood condemned. For before certain men came from James, he was eating with the Gentiles; but when they came he drew back and separated himself, fearing the circumcision party. And the rest of the Jews acted hypocritically along with him, so that even Barnabas was led astray by their hypocrisy. But when I saw that their conduct was not in step with the truth of the gospel, I said to Cephas before them all, "If you, though a Jew, live like a Gentile and not like a Jew, how can you force the Gentiles to live like Jews?" We ourselves are Jews by birth and not Gentile sinners; yet we know that a person is not justified by works of the law but through faith in Jesus Christ, so we also have believed in Christ Jesus, in order to be justified by faith in Christ and not by works of the law, because by works of the law no one will be justified. But if, in our endeavor to be justified in Christ, we too were found to be sinners, is Christ then a servant of sin? Certainly not! For if I rebuild what I tore down, I prove myself to be a transgressor. For through the law I died to the law, so that I might live to God. I have been crucified with Christ. It is no longer I who live, but Christ who lives in me. And the life I now live in the flesh I live by faith in the Son of God, who loved me and gave himself for me. I do not nullify the grace of God, for if righteousness were through the law, then Christ died for no purpose. [23:12] [25:50] [31:41] [34:01] [34:21] [47:14]

Acts 10:9-16
The next day, as they were on their journey and approaching the city, Peter went up on the housetop about the sixth hour to pray. And he became hungry and wanted something to eat, but while they were preparing it, he fell into a trance and saw the heavens opened and something like a great sheet descending, being let down by its four corners upon the earth. In it were all kinds of animals and reptiles and birds of the air. And there came a voice to him: "Rise, Peter; kill and eat." But Peter said, "By no means, Lord; for I have never eaten anything that is common or unclean." And the voice came to him again a second time, "What God has made clean, do not call common." This happened three times, and the thing was taken up at once to heaven. [28:32] [28:37] [29:00] [29:06]

Revelation 7:9
After this I looked, and behold, a great multitude that no one could number, from every nation, from all tribes and peoples and languages, standing before the throne and before the Lamb, clothed in white robes, with palm branches in their hands, [43:36] [43:43]

Observation questions

1. In Galatians 2, what changed in Peter’s behaviour when certain men arrived, and who else was affected by his withdrawal? [31:41]
2. According to Acts 10, what did Peter see in the vision, and what was God’s command to him about what had been called unclean? [29:06]
3. In Galatians 2:14, what does Paul say Peter’s conduct was not in step with, and how did Peter’s actions pressure Gentile believers? [34:01]
4. In Galatians 2:20-21, what reasons does Paul give for why righteousness cannot come through the law? [47:14]

Interpretation questions

1. Peter did not preach a false message with his mouth, but his actions still sent one. How can table fellowship communicate something true or false about the gospel? [32:32]
2. Paul says a person is justified by faith in Jesus Christ and not by works of the law. Why is that truth the key to understanding why Peter’s withdrawal was such a serious issue? [34:21]
3. Justification is an acquittal, not innocence. How does that protect both honesty about human sin and confidence in God’s grace? [36:54]
4. Revelation 7 shows one great multitude from every nation, tribe, people, and language. How does that future picture help explain why separating from fellow believers over old boundary lines clashes with God’s purposes now? [43:43]

Application questions

1. Peter feared the approval of a particular group. Where is the pressure of other people’s opinions most likely to shape choices, friendships, or silence in everyday life right now? [40:14]
2. Christ’s approval frees believers from being ruled by people-pleasing. What might it look like this week to act on that freedom in one real relationship or situation? [42:24]
3. Grace makes one table. Is there anyone in church life who tends to feel distant, awkward, or outside “our group”? What small step could help make room at the table more intentionally? [42:54]
4. Good works are a beautiful way to serve Jesus, but they cannot seal the deal with God. When serving, giving, or helping others, what motives tend to creep in alongside gratitude? [45:56]
5. “If righteousness could be gained through the law, Christ died for nothing.” Are there any habits of thought that still sound like, “Jesus helps, but I also need to prove myself”? [47:47]
6. “I have been crucified with Christ… and the life I now live… I live by faith in the Son of God.” What part of life most needs to be brought back under that truth at the moment: identity, guilt, approval, obedience, or something else? [47:30]
7. A useful question is: what does living out and enjoying God’s grace look like in this situation? What current situation would be worth bringing to that question as a group tonight? [49:19]
