When Paul and Barnabas left Antioch to go out on their first missionary journey, they started a new movement in the book of Acts. They began the last phase of our Lord's great commission. They started to go out to "the uttermost parts of the earth..." (Acts 1:8b KJV). So this constitutes a separate section of this book. We call this series of messages "The Pattern Setters" because, in this section of Acts, you find the pattern for all Christian witness in any age.
