The book of Acts was written by the Greek physician Luke who goes on to record the life of the early Christian church and the followers of Jesus. Here, in the Acts of the Apostles, sometimes also referred to as the Acts of the Holy Ghost, Luke records about thirty years of history from the ascension of Christ into heaven to the imprisonment of the Apostle Paul in a Roman prison. Acts was written around 60 A.D. and was a continuation of the book of Luke, bridging as it were the books of the Gospels and the letters or Epistles of Paul to the early Christian church of that time. Many events such as Pentecost, Peter's sermon's, the martyr of Stephen, miracles of the early church, the conversion of Paul and more are recorded here. The first missionary journeys are also told here, telling of the Apostle Paul's trips throughout Europe and Asia, proclaiming the Gospel of Jesus throughout the known world.
