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:

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


📖 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!”


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…”


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…”


Galatians 6:15 — New Creation Over Badges

“For in Christ Jesus neither circumcision nor uncircumcision avails anything, but a new creation.”


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.”


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.”


Galatians 6:18 — Grace-Filled Benediction

“Brethren, the grace of our Lord Jesus Christ be with your spirit. Amen.”


🧭 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.

📦 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:

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)
