The early church really was a church on the move. It was dynamic and exhilarating and there really was a sense of things happening. There were, undoubtedly, dangerous and challenging times for the early Christians, but they were exciting times as God's Holy Spirit was at work amongst the leaders and the ordinary people. While we may look back with longing to such days, God has called us to serve him with the gospel of his grace in our own day, and we may do so with the help of such instruction as is to be found in this book.
