Galatians: The Heartbeat of the Gospel

Paul's letter to the Galatians has been called the heartbeat of the gospel, and for good reason. Written to congregations Paul himself had planted in the region of Galatia (modern-day Turkey, in Asia Minor), the letter responds to a crisis: after Paul moved on, certain teachers known as the Judaizers came in behind him, claiming that Gentile believers had to keep the Jewish ceremonial law—particularly circumcision—in order to truly be saved. They affirmed Christ, but added "and." They taught grace plus works. The result was a perverted gospel and confused believers.

Paul's response cuts to the very center of Christian teaching: the right distinction between law and gospel. The law shows us our sin and brings us to the end of ourselves; it kills. The gospel proclaims that Christ died and rose for sinners; it brings life and freedom. When the two are mingled, both are lost. As Luther observed, mingling law and gospel "creates more mischief than a man's brain can conceive," and it cuts Christ out. The whole letter, then, is Paul's defense of the truth that we are justified by faith in Jesus Christ alone, apart from works of the law. See Galatians: Lesson 1 and Galatians: Lesson 3.

Paul's Apostleship and the Authority of the Gospel

Paul opens with an unusual urgency about his own credentials: "Paul, an apostle—not from men nor through man, but through Jesus Christ and God the Father, who raised him from the dead" Galatians 1:1. This is not boasting. The Judaizers had men of prestige, heritage, and clout; Paul came alone. They sought to undermine his authority and, with it, the message he preached. Paul answers by appealing not to human commission but to Christ Himself, who appointed him on the Damascus road Acts 9:15 and whose Spirit later set him apart at Antioch Acts 13:1-3. The gospel he preached was not invented or learned secondhand; it came by revelation from Christ. To undermine Paul's apostleship was to undermine the gospel itself. See Galatians: Lesson 2.

The Seriousness of Sin and the Sufficiency of Christ

"Grace to you and peace from God our Father and the Lord Jesus Christ, who gave himself for our sins to set us free from the present evil age" Galatians 1:3-4. To receive that peace, sin must be taken seriously—neither dismissed as trivial nor magnified to despair. Lutherans sit comfortably in the paradox of being simultaneously saint and sinner. As Luther put it, Christ was given "not for petty or imaginary transgressions, but for mountainous sins, not for one or two, but for all, not for sins that can be discarded, but for sins that are stubbornly ingrained." If our sin were small, we would not need Christ. Because it is great, we cling all the more to the One who bore it.

This is why Paul is astonished that the Galatians have so quickly turned to a different gospel. Heretics rarely advertise their errors; they seduce the ear with what flatters human pride—the suggestion that we have something to contribute to our salvation. The defense against such seduction is to be rooted, like good soil, in the Word of God within a faithful community Matthew 13:3-23.

The Council at Jerusalem and the Confrontation at Antioch

Paul recounts going up to Jerusalem with Barnabas and Titus, where the question was settled in the church's favor: Gentiles were not to be compelled to be circumcised for salvation Acts 15. Paul did not go to receive permission; he went to preserve the gospel. He even refused to circumcise Titus, not because circumcision is sinful, but because it was being demanded as a condition of salvation. By contrast, he had Timothy circumcised out of brotherly love, so that nothing would distract Jewish hearers from the gospel Acts 16:3. The difference is motive: love freely yields; legalism demands. See Galatians: Lesson 4.

When Peter later withdrew from eating with Gentile believers at Antioch out of fear of the circumcision party, Paul opposed him to his face Galatians 2:11-14. Peter was not a heretic, but his hypocrisy endangered the principle of Christian liberty. The truth had to stand, even when the conversation was awkward. See Galatians: Lesson 5.

Justified by Faith, Crucified with Christ

At the heart of the letter Paul declares: "We know that a person is justified not by the works of the law but through faith in Jesus Christ" Galatians 2:16. And then comes one of the most personal sentences in all of Scripture: "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" Galatians 2:20.

Read those words for me and print them in capital letters on the heart. The promise is yours. Faith joins you so intimately to Christ that His righteousness, victory, and life become yours, while your sin and death are taken up by Him. This is the blessed exchange. When we look inward we find plenty of sin; when we look to Christ we find ourselves redeemed.

The Spirit and the Foolishness of Returning to the Law

"O foolish Galatians! Who has bewitched you?" Galatians 3:1. Paul presses a piercing question: did you receive the Spirit by works of the law or by hearing with faith? The answer is obvious. Cornelius and his household received the Holy Spirit while Peter was still preaching Acts 10—they did nothing but hear and believe. So Abraham believed God, and it was counted to him as righteousness Genesis 15:6. Faith itself is a gift, "not your own doing… so that no one may boast" Ephesians 2:8-9. To turn back to the law for justification, after beginning in the Spirit, is to crucify Christ in the heart all over again. See Galatians: Lesson 6.

Good Good Works and Bad Good Works

Because Galatians so strongly defends salvation by grace through faith alone, Lutherans are sometimes accused of opposing good works. Not so. Scripture is full of zeal for them Titus 2:11-14; we are God's workmanship, "created in Christ Jesus for good works, which God prepared beforehand" Ephesians 2:10. The decisive question is connection to Christ. Apart from Him we can do nothing John 15:4-5; without faith it is impossible to please God Hebrews 11:6; whatever does not proceed from faith is sin Romans 14:23. A morally impressive deed performed apart from faith—the Pharisee's prayer Luke 18:9-14, the rich young ruler's self-assessment Matthew 19:16-22, or even Paul's pre-conversion résumé Philippians 3:4-8—is a "bad good work." Works flowing from faith in Christ, however imperfect, are a "good good work," for they are God's own doing in us Philippians 2:13. Salvation is never by good works; the redeemed life is always for them. See Galatians: Lesson 7.

The Heartbeat That Will Not Stop

From beginning to end, Galatians sounds the same steady pulse: Christ alone, grace alone, faith alone. The yoke of the law has been lifted; relief, real relief, is ours. We are free—not free to sin, but free to live as new creations in whom Christ Himself dwells. The promise is for you. Take it, hold it, cling to it, and walk in it.
