In Galatians 6:6-18, Paul encourages his listeners to invest their lives in truth. We reap what we sow. If we seek teachers who flatter and entertain us, that is what we will harvest. God is not mocked. He knows what we seek.
In Galatians 5:25-6:5, Paul explains how the fact that we all believe the same gospel translates into our lives as a community. First, he urges us to stop competing with our teammates. Then Paul explains how to respond when someone stumbles on this metaphorical race to glory.
Paul argues we don’t need the Law to keep us from pursuing sin. We have something better. We have the Spirit of God teaching us to pursue goodness.
In the final chapters, he develops his third major theme which is the freedom the gospel brings. Because the gospel solves our two biggest problems, it brings freedom from the law and freedom from slavery to sin.
In the story of Abraham we find two sons, two wives, two covenants, two mountains, and two cities. So we have only two options. One option leads to eternal life in the kingdom of God. The other leads to destruction.
In his fourth argument, Paul appeals to the Galatians to return to the true gospel based on his deep affection and concern for them.
My detailed outline of Galatians along with an overview of Paul’s three main themes.
The Judaizers teach you need to place yourself under the guardianship of the Law. Why would adults want to return the restrictions of childhood? Like a child who has come of age, you have graduated from the guardianship of the Law.
The Law teaches valuable lessons that prepare us for faith and keep us from evil. But, after the Messiah came, we graduated from the protective custody of the Law. All of us receive justification by the same path: faith in Jesus Christ.
Paul argues the Law, which was a deal, does not nullify the promise given to Abraham. In a deal, two parties agree to certain obligations. But a promise is made by one party unconditionally.
In Galatians 3, Paul begins a series of five arguments for justification by faith. In the first two, Paul argues from experience and from the plain teaching of Scripture.
Galatians 2:11-21: Paul includes rebuking Peter as part of his defense. Paul could rebuke Peter because they had the same view of the gospel. This incident serves two purposes: 1) it furthers Paul’s claim that he and the apostles teach the same gospel; and 2) it introduces this issue of whether gentile believers must keep the law.
