The Changed Situation. We have now come to a turning point in the whole situation. The center of work has shifted from Jerusalem to Antioch, the capital of the Greek province of Syria, the residence of the Roman governor of the province. We change from the study of the struggles of Christianity in the Jewish world to those it made among heathen people. We no longer study many and various persons and their labors but center our study upon the life and labors of Paul. The Divine Call. Certain prophets of the church at Antioch were engaged in solemn prayer and worship when the Holy Spirit instructed them to send Paul and Barnabas to do the work to which they were called. Here, then, the Holy Spirit takes charge of the movement. He inaugurates, directs and promotes this work. When the call came it is probable that Paul had but little idea of the magnitude of the work which he was to do. He was not aware that his work and teaching would change the religion and philosophy of the whole world. The Time and Extent of Paul's Journeys. The most of his work was accomplished during three great missionary journeys. The time occupied for these great journeys with the distance traveled has been estimated as follows: the first journey 1400 miles and three years; the second journey 3200 miles and three years; the third journey 3500 miles and four years; or a total of 8100 miles representing ten years of labor. To this must be added his journey to Rome which required a whole winter and was about 2300 miles and many side trips of which we have no record. It is also commonly thought that he was released at the end of two years at Rome and again entered upon mission work that probably lasted four years and carried him again into Macedonia, Asia Minor, Crete and Spain. The First Missionary Journey. (Acts, chs. 13-14). The company consisted of Saul and Barnabas and John Mark. They went by way of the isle of Cyprus and at Paphos the capital of the island the governor was converted and Saul was afterward called Paul. They reached Pamphylia and Pisidia in Asia. John Mark left them in Pamphylia and returned home. In the cities of Pisidia Paul was persecuted and opposed. At Antioch he made a complete break with the Jews and at Lystra they stoned him until they thought he was dead. From Derbe the missionaries retraced their steps except that they did not go through Cyprus on the return to Antioch. Their stay at Antioch was marked by an important church council at Jerusalem, Acts 15:1-35. At this council it was decided that Gentile Christians were not bound by the requirement of the Jewish law. This decision was instrumental in determining that Christianity was not simply a new branch of Judaism but was a new religion.
