Galatians 6:11–18 – Boast Only in the Cross
📖 Passage
Galatians 6:11–18
Read Galatians 6:11–18 (NKJV)
🧠 Context & Background
As Paul closes his letter, he takes the pen into his own hands (“with large letters,” v.11), underlining his personal passion and authority. The stakes are laid bare:
- The Agitators’ Motives (vv.12–13): False teachers compel circumcision, not out of zeal for God’s law, but to avoid persecution for the cross and to boast in outward marks. Their religion is driven by fear of man and desire for applause.
- Paul’s Sole Boast (v.14): In contrast, Paul exults only in the cross of Christ—the place where the world is crucified to him and he to the world. The cross shatters every false ground of confidence.
- New Creation Reality (v.15): Neither circumcision nor uncircumcision counts for anything; what matters is the new creation—God’s Spirit-wrought people, transformed by grace.
- Rule of Peace and Mercy (v.16): This new creation becomes the rule (κανών), the guiding line of Christian identity and fellowship. Those who walk by it receive peace and mercy, God’s covenant blessings.
- Marks of Jesus (v.17): Paul bears not the badges of legalism but the scars of suffering for Christ. His body itself testifies to authentic discipleship.
- Final Word of Grace (v.18): The letter ends as it began—with grace. Everything depends on the crucified and risen Christ, and the community lives by His undeserved favor.
Wrap-up: Galatians begins with astonishment at a distorted gospel (1:6–9) and ends with the gospel’s essence: grace in Christ alone, the cross as our only boast, and the new creation as our identity.
🌿 Key Themes
- Only-Boast: the Cross — The world glories in marks of status, but Paul glories only in the cross of Christ, where salvation was secured and the world crucified to him (v.14).
- New Creation Over Badges — Neither circumcision nor uncircumcision has saving power. The decisive reality is the new creation—God’s Spirit-renewed people (v.15).
- The Rule (κανών) — This “rule” is the straight line of gospel identity: peace and mercy flow to all who walk by the standard of the cross and new creation (v.16).
- Marks of Jesus — Paul carries not the outward marks of Law observance but the scars of suffering for Christ—proof of authentic discipleship and allegiance (v.17).
- Grace-Filled Benediction — Paul both opens (1:3) and closes (6:18) with grace. The gospel begins, continues, and ends in unearned favor—Christ for sinners.
📖 Verse-by-Verse Commentary
Galatians 6:11 — Large Letters, Personal Emphasis
“See with what large letters I have written to you with my own hand!”
- Personal signature: Paul takes the pen himself, signaling urgency and ownership.
- Large letters: Possibly due to poor eyesight (cf. 4:15), or as a deliberate emphasis—like underlining—so the conclusion lands with force.
Galatians 6:12–13 — The Motives of the Agitators
“As many as desire to make a good showing in the flesh, these would compel you to be circumcised, only that they may not suffer persecution for the cross of Christ…”
- Boasting in the flesh: Their aim is to look good outwardly and avoid stigma.
- Fear of persecution: Circumcision shielded them from Jewish hostility, making the gospel seem less offensive.
- Hypocrisy: They don’t even keep the law fully, but want others circumcised so they can boast in numbers.
Galatians 6:14 — Paul's Sole Boast: the Cross
“But God forbid that I should boast except in the cross of our Lord Jesus Christ…”
- Radical reversal: In Paul’s world, the cross was a symbol of shame; yet he makes it his only boast.
- Crucified world: Through the cross, the world’s claims to status and approval are dead to Paul—and he to the world.
- Christ-centered identity: The cross is both the ground of justification and the pattern of discipleship.
Galatians 6:15 — New Creation Over Badges
“For in Christ Jesus neither circumcision nor uncircumcision avails anything, but a new creation.”
- Decisive reality: Religious badges are powerless to save. What counts is regeneration—God making people new (cf. 2 Cor 5:17).
- Covenant shift: The gospel does not tweak the old system; it inaugurates new creation in Christ.
Galatians 6:16 — The Rule of Peace and Mercy
“And as many as walk according to this rule, peace and mercy be upon them, and upon the Israel of God.”
- The rule (κανών): A straight standard—the cross and new creation define Christian life.
- Blessing invoked: Peace and mercy mark those who embrace this rule.
- Israel of God: Likely referring to the church—Jews and Gentiles who share in the promise by faith.
Galatians 6:17 — The Marks of Jesus
“From now on let no one trouble me, for I bear in my body the marks of the Lord Jesus.”
- Stigmata: Not mystical wounds but literal scars from persecution (cf. 2 Cor 11:23–25).
- True credentials: Paul’s body bears proof of allegiance to Christ, in contrast to the empty marks of circumcision.
Galatians 6:18 — Grace-Filled Benediction
“Brethren, the grace of our Lord Jesus Christ be with your spirit. Amen.”
- Final note: Paul ends as he began (cf. 1:3)—with grace.
- Fraternal tone: He still calls them “brethren,” binding rebuke and affection together.
- Grace alone: The last word of Galatians is the first word of the gospel—God’s unearned favor in Christ.
🧭 Who Is “the Israel of God”? (v.16)
Two main readings appear in Reformed circles. Both reject law-badges as the basis of belonging and honor Christ alone.
1) Believing Jews within the church (two groups in v.16):
- Reading: “Peace and mercy be upon all who walk by this rule (the whole church), and (καί) also upon the Israel of God (i.e., Jewish Christians).”
- Support: The coordinate καί can distinguish groups; this fits Paul’s concern for Jew–Gentile unity while honoring Jewish believers who embrace the new-creation rule.
2) The whole church as God’s Israel (appositional reading):
- Reading: “Peace and mercy be upon all who walk by this rule, that is, upon the Israel of God.”
- Support: In Galatians, the people of God are defined by faith/Spirit/promise (3:7, 26–29; 4:26, 28). The “Jerusalem above” (4:26) and being “Abraham’s seed” in Christ (3:29) point to the church (Jew + Gentile) as God’s true Israel—the eschatological people formed by the new creation, not by circumcision.
Which is best in this context?
Given Paul’s relentless argument that badge-religion divides and that new creation unites (3:26–29; 5:6; 6:15), the appositional view fits the immediate flow: those who “walk by this rule” are “the Israel of God.” It highlights one people of God, in Christ, defined by new creation, not by circumcision. Nevertheless, the first reading remains theologically orthodox and pastorally charitable toward Jewish Christians. Either way, peace and mercy rest only on those who embrace the cross and new creation.
🔍 Trusted Insight (Charles Spurgeon)
“The cross is the ladder to heaven. The cross is the key to paradise. The cross is the light in the darkness, the healing of the nations, the joy of the saints, and the terror of hell.” — Charles Spurgeon, Sermon No. 1702
Summary: For Spurgeon, the cross is not one theme among many but the center of Christian glory and hope. Paul’s final boast mirrors this: every other ground of pride must fall, for only in the cross does God create a new people and open the way of life.
❓ Common Objections
- Is Paul dismissing circumcision and Jewish identity as worthless?”
Paul is not scorning Israel’s history or the Law. He insists that circumcision and uncircumcision alike cannot justify (v.15). What matters is the new creation in Christ, which fulfills what the Law pointed toward. - “Is boasting in the cross morbid? Shouldn’t we celebrate life, not death?”
The cross was a shameful instrument of execution, yet Paul boasts in it because through it Christ destroyed sin, conquered death, and reconciled sinners to God. It is precisely in Christ’s death that true life is secured. - “Who is the ‘Israel of God’ in v.16? Is Paul excluding ethnic Israel?”
Paul is not erasing Jewish identity but redefining true covenant membership. The “Israel of God” refers to the people of promise—Jews and Gentiles alike—who belong to Christ by faith (cf. 3:7, 29). - “Does Paul glorify suffering when he speaks of the ‘marks of Jesus’ (v.17)?”
No. He is not romanticizing pain but identifying the authentic credentials of an apostle. His scars prove loyalty to Christ and contrast with false teachers who boast in externals but avoid the cross’s cost.

- What do the **marks of Jesus** (v.17) teach about authentic ministry? ---
🔍 Definitions
- Boast/Glory (καυχάομαι) — To place one’s confidence and joy in something; for Paul: the cross alone (v.14).
- New Creation (καινὴ κτίσις) — Eschatological life inaugurated in union with Christ (v.15).
- Rule (κανών) — Standard/measure; here, the gospel-pattern of new creation (v.16).
- Israel of God — God’s covenant people as defined by Christ’s new-creation work; either (a) the church as a whole (Jew + Gentile) or (b) Jewish Christians within it (v.16).
- Marks (στίγματα) — Visible scars from persecution for Christ, authenticating apostolic ministry (v.17).
🌎 Worldviews
- Religious Pride: Many worldviews boast in badges—whether rituals, moral achievements, or spiritual credentials. The agitators exalted circumcision as a mark of superiority. Paul declares such boasting empty, replaced by glorying in the cross.
- Cultural Approval-Seeking: In every age, people shape their religion to avoid offense and gain acceptance. The false teachers sought to evade persecution by minimizing the scandal of the cross. The gospel worldview accepts reproach, for only the cross saves.
- New Creation Identity: The world defines worth by status, heritage, or performance. Paul proclaims that what counts is neither circumcision nor uncircumcision but the new creation. Believers live as a people of the age to come, defined by grace, not flesh.
- Marks that Matter: Cultures prize outward marks of success, power, and beauty. Paul points instead to the marks of Jesus—suffering for Christ as true allegiance. What the world despises becomes the badge of honor in God’s kingdom.
- Grace as the Last Word: Competing worldviews close with demands, fear, or pride. The gospel closes with grace (v.18)—the unearned favor of God in Christ. Grace is not the introduction to the Christian life but its final word.

📦 Final Wrap-Up
Galatians begins with astonishment that the church was drifting toward “another gospel” (1:6–9) and ends with Paul’s declaration that the only true boast is the cross of Christ (6:14). Across the letter, Paul has:
- Defended the gospel of grace as received by revelation, not human invention (ch. 1–2).
- Shown that believers are justified by faith, not by works of the Law, and are adopted as children of promise (ch. 3–4).
- Urged the church to stand firm in freedom, rejecting both legalism and license, and to walk by the Spirit in love (ch. 5).
- Summoned the community to bear one another’s burdens, sow to the Spirit, and persevere in doing good (ch. 6).
The closing vision is clear: religious badges count for nothing; what matters is new creation (6:15). The cross of Christ has ended boasting in the flesh, birthed a Spirit-filled people, and secured the blessing promised to Abraham for all nations.
Galatians, then, is not merely Paul’s defense of doctrine but a pastoral call: cling to Christ, boast only in His cross, walk by the Spirit, and live as the new creation until the final harvest.
“The grace of our Lord Jesus Christ be with your spirit, brothers. Amen.” (6:18)
