2Tim.4What a faithful disciple! I believe that Luke was one of Paul's converts on his first missionary journey, in the city of Antioch in Pisidia1. Luke was a Greek, uncircumcised, a Gentile who was attached to the synagogue in Antioch (not Syrian Antioch where the disciples were first called Christians). If you will read Acts 13:13-52 with this possibility in mind, you should glean similar insights. The event is described by an eyewitness, not by one relaying an account heard from someone else. Note v. 16:
 Luke alone is with me.
So Paul stood up and motioning with his hands, said, "Men of Israel, and you that fear God, listen . . .."Two things are significant. The detailed description of Paul standing up and motioning with his hands suggests an eyewitness, especially since it was the general rule in synagogues that the speaker sat rather than stood. Then there is that address to "you that fear God." This is not a general address, but is made to a specific category distinct from the "men of Israel." We know from other sources that the synagogues in Gentile communities such as Antioch often included in their congregations Gentiles of good will who also believed in God as taught by the Jews. These were admitted as members in the special category of "God fearers." They were converts to Judaism, usually from the worship of idols, who did not want to become fully Jews by being circumcised, nor did the Jews encourage them to do this. I believe Luke was one of them.
 strengthening the souls of the disciples, exhorting them to continue in the faith, and saying that through many tribulations we must enter the kingdom of God.Do you notice the "we?" I see Luke sitting there, rejoicing as he listened intensely to Paul.
Acts.16Again, Luke is with them! See the "we?" I conclude that, on Paul's second journey, while passing through Antioch, Luke joined the entourage and thereafter stayed as close to Paul as he could. He journeyed with him on the last, fateful journey to Jerusalem (21:15f). He met the Apostles and James, the Lord's brother (v. 21:18). Then he later journeyed with Paul to Rome and remained with him there.
 And when he had seen the vision, immediately we sought to go on into Macedonia, concluding that God had called us to preach the gospel to them.
This did not include Paul. Who could these persons be if not the apostles, or at least others who were very close to Jesus, such as his mother or his brethren?
