As I read this book, I am reminded of Philip and the Ethiopian.
Acts 8: 26 Now an angel of the Lord said to Philip, “Go south to the road—the desert road—that goes down from Jerusalem to Gaza.” 27 So he started out, and on his way he met an Ethiopian eunuch, an important official in charge of all the treasury of Candace, queen of the Ethiopians. This man had gone to Jerusalem to worship, 28 and on his way home was sitting in his chariot reading the book of Isaiah the prophet. 29 The Spirit told Philip, “Go to that chariot and stay near it.” 30 Then Philip ran up to the chariot and heard the man reading Isaiah the prophet. “Do you understand what you are reading?” Philip asked. 31 “How can I,” he said, “unless someone explains it to me?” So he invited Philip to come up and sit with him.
