This section is one of the richest sections of Paul’s writings, and consists of two basic moves:
-The argument from experience (3:1-5). Paul will argue from what the Galatians experienced at their conversion and afterwards to argue for the sufficiency of Christ.
-The argument from Scripture (3:6-14). Paul will argue that it was always God’s intention to save Jew and Gentile alike through faith by the work of Jesus.
In many respects Paul’s arguments in this chapter are similar to those made at the Jerusalem Conference in Acts 15.
-Paul and Barnabas argued from experience, the signs and wonders performed among the Gentiles (Acts 15:12). Peter also argued from what was experienced by Cornelius and his household (Acts 15:7).
-Peter also argued that it was God’s will that both Jew and Gentile be saved by faith (15:9, 11), and that the Jews had historically failed to keep the Law (15:10).
-James argued that the prophets had foreseen the day when the Gentiles would come in to the family of God (15:15-17).
