What does Acts 9:27 mean?
Saul, the violent, driven persecutor of the church has become Saul, the intense defender of Christianity. Later, he will go by his Greek name, Paul (Acts 13:9). Saul met Jesus on the road to Damascus, about 133 miles north of Jerusalem. Where once he had used his training as a Pharisee and his complete devotion to destroy the church, he now shows Jews how Jesus is the fulfillment of the prophecies of the Jewish Messiah. After teaching in Damascus, he has come to Jerusalem and is ready to meet the leaders of the church. But the apostles are scared. They know who he is and what he has done, and they're not ready to trust a conversion they didn't witness (Acts 9:1–26).Barnabas is one of the first members of the church. His given name is Joseph, but he goes by a name which means "son of encouragement," which fits him very well (Acts 4:36–37). He is from the island of Cyprus, but apparently heard about Jesus while traveling to Jerusalem and quickly became fully devoted.
"Bold" is a good word to describe Saul's ministry. On his first mission trip, when he and Barnabas go to Cyprus and speak to the proconsul, Saul will tell a Jewish magician, "You son of the devil, you enemy of all righteousness, full of all deceit and villainy, will you not stop making crooked the straight paths of the Lord?" (Acts 13:10). When he is presented with a chance to speak with King Agrippa, he does so eagerly (Acts 26). And when Peter stops eating with Gentile Christians for fear of disappointing legalistic Jewish Christians, Saul reprimands him in public (Galatians 2:14).
After meeting with the apostles, Saul will continue to preach boldly in Jerusalem—to the point that the Greek-speaking Jews take notice. This is the same group that found Stephen so hard to debate that they murdered him (Acts 6:8–15; 7:54–60). And the same group that will eventually have Saul arrested in Jerusalem (Acts 21:27–36).
