What does Galatians 1:24 mean?

Paul has just described how he had been known by the Christians in Jerusalem and Judea more by reputation than in person. The church in that region heard the stories of his radical transformation. Back when he was a Pharisee in Jerusalem, he had led the effort to destroy the church of God by chasing down and arresting Christians and even advocating for their execution. Every believer who knew of Paul—then called Saul—likely feared him for that reason.

Then suddenly, this persecutor was gone from the scene. As Paul has described, after God revealed to him the Son (Acts 9:1–22), and had commissioned him to preach to the Gentiles, Paul had gone off by himself for three years and then off to Syria and Cilicia to preach the gospel. Eventually, the Judean Christians heard about this Paul, as well. He now told people how to have their sins forgiven by God's grace through faith in Christ.

How did the Christians in and around Jerusalem respond to the reported change? Paul reports that they praised or glorified God because of him. As his letters often express, bringing praise and glory to God is one of the ultimate goals of his life.
