THESIS
There is one gospel, God’s, revealed by Christ, affirmed in Jerusalem, and guarded in Antioch. We are justified by faith in Jesus, not by works of the law. Returning to performance-thinking empties the cross of its power.
INTRO: WEEK TWO — INTO THE LETTER
Welcome back to Galatians. In Week 1, we mapped the stakes, now we move into the body of the letter. Paul skips pleasantries and sounds the alarm: the Galatians are deserting the true gospel for a counterfeit. This is not a lifestyle upgrade but Christ’s rescue from the present evil age and the arrival of His kingdom. Because the stakes are life and death, Paul anchors his message in revelation from Christ, shows that the apostles in Jerusalem affirm it, and confronts any practice that edits grace. Keep reading, for counterfeits starve, but the true gospel feeds.
TEACHING & EXPOSITION
1) Galatians 1:1–10 — The Line Between Real and False
Paul declares the gospel at the start: Christ gave Himself for our sins to deliver us (1:4).
He draws the line: there is no second version; to accept a counterfeit is to desert Christ.
False teachers shrink grace by adding requirements like circumcision, enlarging their own authority. Paul refuses to let that happen.
Anchor truth: Urgency is love when the house is on fire—Paul’s sharp words aim to rescue the Galatians from a false gospel.
2) Galatians 1:11–24 — Revelation, Not Invention
Paul’s gospel is not from man; he received it by direct revelation from Jesus Christ (1:11–12).
This was more than a Damascus moment; an ongoing, definitive revelation formed his message.
He cites his past as a persecutor. His transformation is Exhibit A that grace is real.
Timeline of Paul’s Early Ministry (Acts and Galatians)
Acts 9: Damascus encounter, healing through Ananias, baptism, early strengthening in Damascus.
Galatians 1: Arabia, return to Damascus, three years later to Jerusalem (meeting Peter and James), then to Syria and Cilicia.
Result: The hunter now preaches the faith he tried to destroy.
Meaning: Paul is not unstable but remade. His authority is Christ-given, not humanly derived.
3) Galatians 2:1–10 — Unity in Jerusalem (Private on Purpose)
Fourteen years later, Paul returns with Barnabas and Titus to lay out his gospel privately, so he had not “run in vain.”
Titus, a Gentile, was not compelled to be circumcised (2:3) — a practical test case for the gospel’s freedom.
Circumcision, Abraham’s covenant sign before Moses, was central to the debate, yet Gentiles do not need to become Jews to follow Christ.
God does not judge by external appearance (2:6). The pillars recognize grace in Paul, extend the right hand of fellowship, and ask only that he remember the poor (2:10).
Verdict: It is God’s gospel, and Jerusalem affirms it.
4) Galatians 2:11–14 — The Table Test (Paul vs. Peter)
Picture a long table in Antioch. Bread torn. Blessing given. Gentiles and Jews eating as one. A new kind of family humming in the room. Visitors arrive from James. A chair scrapes back. Peter steps away. The room feels it. So does Barnabas. So does Paul.
Peter had eaten with Gentiles because Christ, not Torah boundary markers, now defines the table. When men came from James, Peter withdrew to look good in their eyes, and others followed. Paul opposed Peter to his face (2:11). Why? Because actions preach. Peter’s withdrawal implied, in practice, “You are not fully in unless you bear the mark of circumcision.”
Paul draws the line to keep the table whole. The gospel’s truth is at stake. Even an apostle cannot act as if grace is partial. Public compromise demands public correction.
5) Galatians 2:15–21 — Justification by Faith, Stated Three Ways
Paul states the center three times in 2:16:
A person is not justified by works of the law but through faith in Jesus Christ.
We believed in Christ to be justified by faith, not by works of the law.
By works of the law no one will be justified.
He anticipates the objection (2:17): if justification is by faith apart from the law, does Christ promote sin? Jewish critics might fear lawlessness, but Paul says, “Absolutely not.” He will develop freedom and holiness in chapter 5.
He lands with the confession that rewrites a life (2:19–21):
Through the law I died to the law, so I might live for God.
I have been crucified with Christ. I no longer live; Christ lives in me.
If righteousness could be gained through the law, then Christ died for nothing.
Remember the audience: They had already embraced the gospel. Returning to law-logic for favor treats the cross as unnecessary.
THE LAW, THE CROSS, AND US
The law is good, revealing God’s holiness and our sin, but it cannot give life. Christ fulfilled the law and bore its penalty at the cross. Life comes by the Spirit in union with Christ, not rule-keeping.
The law still instructs the believer as a guide to God’s will, but never as a ladder to earn righteousness.
Circumcision is not our battleground—performance is. We quietly build scorecards: attendance streaks, serving hours, giving totals, “clean” weeks, or public influence (platform, role, or reach). These can be good gifts, but they are never grounds for acceptance.
HEART CHECKS
Motive: Do I serve to be loved, or because I am loved?
Identity: Do my successes swell me and failures shrink me?
Refuge: When I sin, do I run to Christ or stall until I perform better?
Community: Do my habits imply others need my markers to be fully in?
Courage: Where am I retreating, like Peter, to please others?
Summary: We do not obey to become accepted; we obey because we are.
DEVOTION
Acts 26: Festus calls Paul insane. He isn’t. He is a sane man in a mad world, remade by grace.
Acts 10: Peter learns that no person is unclean. In Antioch he forgets under pressure. Paul loves him enough to tell the truth in public.
Prayer: Lord Jesus, anchor my heart in grace. Stop my seeking applause. Break my scorecards. Let my life preach what I confess.
KEY TAKEAWAYS
The gospel is from God, revealed by Christ, not crafted by consensus.
Jerusalem affirmed the message, no extra boundary markers required.
Antioch protected the message, actions must match confession.
Justification is by faith in Jesus, not by works of the law.
The law reveals, the cross redeems, the Spirit gives life.
REFLECTION CHALLENGE
Name one place this week where you are tempted to earn what Christ has already given. Write a short plan: the trigger you expect, the truth you will speak, and the next faithful action you will take.
Example: If I’m tempted to seek approval by overworking, I’ll remind myself, “In Christ, I am fully loved,” and I will stop, pray, and leave my desk at a sane hour.
Discussion Questions
1) How does Paul’s timeline (Damascus, Arabia, Jerusalem, Syria/Cilicia) strengthen your confidence that the gospel is Christ-given?
Paul’s story isn’t rushed or convenient. Revelation, solitude, testing, and apostolic recognition form a through-line that looks less like spin and more like sovereignty.
2) Why is Titus not being circumcised a watershed moment, and what are today’s “boundary markers”?
Titus is the live test: no add-ons to the cross. Today’s markers might be style, tribe, education, platform, politics, or spiritual “metrics.” None can sit next to Jesus as entry requirements.
3) Where are you most tempted to step back from the “table” for the sake of appearances?
Fear edits fellowship. The chairs we quietly remove preach a counterfeit gospel. Name the room, the faces, and the pressure you feel there.
4) Read Galatians 2:16 aloud. What shifts when justification by faith becomes your daily reality?
The scoreboard turns off. Repentance speeds up. Joy rises. Obedience becomes response, not currency.
5) How do we guard freedom from turning into license on one side and legalism on the other?
Stay near the cross and walk by the Spirit. Freedom without the Spirit drifts to self. Zeal without the cross calcifies to law.
6) “Christ lives in me.” What habit will help you practice that reality this week?
Choose one small, repeatable rhythm—Scripture before screen, a midday prayer, confess-and-run-to-Christ, or a quiet act of costly love—and let it preach union over performance.
AS WE WRAP UP — WEEK 2
Paul’s gospel is Christ-revealed, apostle-affirmed, and non-negotiable. Jerusalem confirms the message; Antioch protects it. We are justified by faith, not performance, and our conduct must match that confession—no add-ons, no quiet retreats from the table.
Ahead to Week 3 (Galatians 3):
Paul opens the Scriptures to prove this has always been God’s way—Abraham before the law, promise over performance, Spirit over flesh. We’ll see how blessing comes by faith and why the law can expose sin but never give life.
