Most Christians know very little about what has happened in the spread of Christianity since Pentecost.
The book of Acts in the New Testament tells a little about Peter’s witness and a little more about Paul’s. After that, what happened? We don’t know—until we come to our own time.
This book helps to fill in the gaps. The amazing spread of the Christian movement far beyond the boundaries of the Roman Empire in the first thousand years after Christ, the irrepressible movements of the Holy Spirit in Christian witness in every part of the globe in the second thousand years, culminating in the astonishing global spread of the faith in the past 300 years—this is our priceless spiritual heritage.
