So Philip ran to him and heard him reading Isaiah the prophet and asked, “Do you understand what you are reading?” And he said, “How can I, unless someone guides me?” And he invited Philip to come up and sit with him. – Acts 8:30–31
As one of the top blokes in Jerusalem church, Philip was inevitable busy with the new-planted Jerusalem mega-church. If he had had his own way, he would have stayed in Jerusalem helping to disciple the 3000 new converts. Plus, he was one of the seven appointed to be in charge of the social justice department in the church (Acts 6). However, the Spirit had a different plan for him.
