Apparently, Paul and his missionary troupe went into the synagogues, and attempted to attract a following with their great speaking gifts, but failed miserably. This must surely have been disheartening, except for the fact Paul knew he had been called in the vision. So, after a number of days, he did something quite surprising, yet not uncommon for him. He went to visit a church that had no Pastor... yes, that's what it was you see.
Acts 16:13 And on the sabbath we went out of the city by a riverside, where prayer was accustomed to be made; and we sat down, and spoke unto the women who met there.
There by the riverside, a group of women who had no Pastor, and seemingly no building, met for worship services of their own. It also seems they allowed Paul to speak before their little congregation. There Paul made his first European convert of a business woman named Lydia, and she began to be the first major financial contributor to his ministry. God works in mysterious ways! The minister without a mission field now found a place in a church without a Pastor. It was as if Paul had come to Europe for such a church as this! And, who was the man in his vision? Perhaps he was the governing angel of that region as in the book of Daniel. Angels are responsible for different regions, though they have not yet been given permission to preach the gospel. The governing angel could have been sent to get Paul to come preach, since this congregation was praying to God for a Pastor. Only God knows!
