Paul Takes the Gospel to the World

After the Resurrection, Jesus spent approximately 40 days talking to his disciples and other followers. He then took his disciples to the Mount of Olives, and commanded them to go spread the Gospel to all the world.
Approximately 10 days later, on the Day of Pentecost, the Holy Ghost fell on 120 followers of Christ, and the Church was born. Finally, it was time for them to obey Christ's command to evangelize the world.
While this book discusses the evangelistic efforts of a number of Apostles, it is primarily focused on the Apostle Paul and his missionary journeys. Paul is believed to be the author of as fourteen of the twenty-seven Books of the New Testament. This fact alone, places Paul in a position of great importance among all the other Apostles.
