In Acts 8, we see a shift in the spread of the Jesus movement. The persecution, culminating in the martyrdom of Stephen, caused the Church to scatter, and the message to spread to surrounding nations and people groups. This is all because a small group of people listened to the prompting of the Holy Spirit and did what he asked them to do.
This is particularly on display in the life of Philip, who has the opportunity to tell people he never thought he'd meet all about Jesus. Through his interaction with a man from Ethiopia, we learn that when you are following the voice of the Spirit, he will take you to people and to places you never thought you'd go.
