After the favourable decision of the Council at Jerusalem, Paul enjoyed a period of tranquillity at Antioch which must have been one of the happiest times of his life. The controversy over membership of Gentiles had been resolved, and his brothers and sisters, both Jew and Gentile, could grow together in knowledge, love and grace.
Eventually, however, the urge to return to his work of preaching seized him once more, and he held a consultation with his friend Barnabas. "Let us return" he suggested, "and visit the brethren in every city where we proclaimed the word of the Lord, and see how they are" (Acts 15:36 ). Barnabas was happy to go, but insisted they should take his relative John Mark as their assistant. An unhappy quarrel developed, because although Mark had gone with them during their first expedition, he had abandoned the work after they left Cyprus and returned to Jerusalem. Paul wanted someone more reliable; Barnabas stuck up for his young cousin. It is surprising, after working together for so many years, that the two veterans should have had such an argument, but neither would give way, and a rift developed which could not be healed. We are left with the embarrassing spectacle of the partners going separate ways. Barnabas and Mark set off for Cyprus, his native island, while Paul teamed up with Silas, who had moved to Antioch from Jerusalem. It should be added that in later years Mark must have redeemed himself in Paul's eyes, for later he is mentioned with approval in three of Paul's letters. We all make mistakes when we are young, and no one deserves to be branded for life because of an early weakness. Besides, Paul himself probably mellowed as he got older.
Paul and Silas spent some time in Galatia, visiting their old friends and passing on the decisions of the elders at Jerusalem. At Lystra Paul invited a young disciple called Timothy to join his band. Timothy became his assistant, replacing John Mark, and stayed faithful to the apostle's service right to the end of Paul's life. He became as close as a son, and Paul's two letters to Timothy are the most personal and tender in the New Testament.
At this stage Paul seems to have been given strong hints about where he should go next. The record in Acts is cryptic – they were "forbidden by the Holy Spirit to speak the word in Asia" … "they attempted to go into Bithynia, but the spirit of Jesus did not allow them". "A vision appeared to Paul in the night. He saw a man of Macedonia … saying 'come over to Macedonia and help us'" (Acts 16:7, 8, 9 ). Evidently the Lord Jesus was deciding their priorities. One result of this manoeuvring was a stay at Troas, a sea port on the northwest coast of Turkey, where someone else joined Paul's travelling company. The fact is not underlined, and the person is not named, but as we read through Acts chapter 16 the grammar alters abruptly between verse 9 and verse 10. It changes from 'they', in the third person, to 'we', in the first person plural. With one brief exception, it stays that way for the rest of Acts. The implication is that the writer of the book of Acts, Luke, is now reporting to us what he experienced firsthand. We thus discover that Luke, the doctor, came from Troas. His presence during Paul's journey is confirmed by occasional mention of his name in Paul's letters.
The province of Macedonia was part of Greece, on the opposite side of the Aegean Sea to Troas. Paul boarded a ship and sailed part of the way, coasting northwards in two days to Neapolis, not far from modern Thessalonika, averaging 75 miles per day. This excellent time implies a following wind or, as Luke puts it, "a direct voyage" (Acts 16:11) . As they landed at Neapolis, the travellers crossed over an invisible boundary into what we now call Europe. The gospel was marching west.
Philippi, a few miles inland, was Paul's next stop. There was no synagogue in that city, but the Jews who lived there met for prayer outdoors on the bank of a river. By coincidence, a business woman from Thyratira, 300 miles south, was among the worshippers. Lydia was a trader in purple cloth, and may well have come to Philippi looking for customers. She was deeply moved by Paul's quiet reasoning, and was eventually baptised, along with other members of her family.
We do not know how long Paul spent at Philippi, but his sojourn there came to an abrupt and dramatic end. He had just healed a mentally disturbed slave girl. Her masters, annoyed because people used to pay them for her to tell their fortunes, dragged Paul and Silas before the magistrates of the city.
