Galatians 2:18: Faith guidance?
How can Galatians 2:18 guide us in maintaining our faith in Christ?

Verse at the Center

“If I rebuild what I have already torn down, I prove myself to be a lawbreaker.” (Galatians 2:18)


Setting the Context

• Paul is standing up to Peter, defending the gospel of grace.

• The “lawbreaker” he has in mind is anyone who tries to re-erect the old system of law-keeping for acceptance with God after trusting Christ.

• Verse 18 sits between Paul’s reminder that we died to the law (v. 19) and his famous declaration, “I have been crucified with Christ” (v. 20).


Core Truth of Galatians 2:18

• Christ’s finished work tore down the wall of legal requirements as a means of justification.

• Trying to rebuild that wall—adding human effort to divine grace—makes us transgressors because it denies the sufficiency of Christ’s sacrifice.

• So, maintaining faith means refusing to put confidence back in religious performance or old patterns of sin.


What “Rebuilding” Looks Like Today

• Trusting in church attendance, rituals, or Bible knowledge to earn favor with God.

• Measuring spiritual worth by outward comparisons rather than Christ’s righteousness.

• Slipping back into sins we once renounced and rationalizing them instead of confessing and forsaking them (2 Peter 2:22).

• Letting guilt or shame dictate our standing instead of Christ’s atonement (Hebrews 10:14).


Maintaining Faith Through the Finished Work of Christ

• Remember Galatians 2:19—“For through the law I died to the law so that I might live to God”. Dead people don’t renovate tombs; they live new lives.

• Embrace Galatians 2:20—our old self was crucified, and now “the life I now live in the flesh I live by faith in the Son of God.”

• Celebrate Romans 7:4—“you also died to the law through the body of Christ, that you might belong to another.”

• Rehearse the reality that justification is a completed act (Romans 5:1).


Practical Steps for Staying on Gospel Ground

• Daily remind yourself of your position: accepted “in the Beloved” (Ephesians 1:6).

• Saturate your mind with Scripture that declares Christ’s sufficiency (Colossians 2:13-14).

• Confess quickly when you catch yourself relying on works or slipping into old sins; receive fresh cleansing (1 John 1:9).

• Fellowship with believers who emphasize grace and truth (Hebrews 10:24-25).

• Serve out of gratitude, not to earn standing—“the love of Christ compels us” (2 Corinthians 5:14).


Encouragement from Related Passages

2 Corinthians 5:17—“Therefore if anyone is in Christ, he is a new creation; the old has passed away; behold, the new has come!”

– Your past is dismantled; don’t rebuild it.

Hebrews 10:26—deliberate sin after receiving the knowledge of the truth brings loss of joy, not loss of salvation—another warning against rebuilding.

Colossians 2:6—“Therefore, just as you have received Christ Jesus as Lord, continue to walk in Him.”

– We began by faith; we stay by faith.


Living Verse 18 Daily

• Each time you’re tempted to trust religious effort or revisit forgiven sin, let Galatians 2:18 sound the alarm: “Don’t rebuild—Christ already tore that down!”

• Stand firm in grace, keep looking to the cross, and enjoy the freedom Christ purchased for you.
