The Book of Acts
The book of Acts is known as 'the birth of the church'. Acts recounts the story of
the early church from the time of Jesus' ascension to Paul's arrival as a prisoner in Rome. Acts was written by the author of Luke's gospel, Luke. Although the author does not name himself, evidence from the book itself proves that the author was Luke.
Luke was a physician. Scriptural evidence of this includes Colossians 4:14: "Our dear friend Luke, the doctor, and Demas send greetings." Luke often used medical language. For instance, he finds the sailors bandaging the ship in Acts 27:17: "When the men had hoisted in aboard, they passed ropes under the ship itself to hold it together.
Fearing that they would run aground on the sandbar of Syrtis, they lowered the sea
anchor and let the ship be driven alone." These two verses along with others in the
scripture prove that Luke was a doctor. Some even think that Luke was the first medical missionary.
Luke was often a traveling companion of Paul. Luke served as a personal comfort to Paul. Luke appears to travel very often, and he is very familiar with nautical terms. This is supported in Acts 16:10-12: " (10) After Paul had seen the vision, we got ready at once to leave for Macedonia, concluding that God had called us to preach the gospel to them. (11) From Troas we put out to sea and sailed straight for Samothrace, and the next day on to Neopolis. (12) From there we traveled to Phillipi, a Roman colony and the leading city of that district of Macedonia. And we stayed there several days." Because it is written
that Luke was a doctor, and that he and Paul were called by God to preach the gospel, it is evident that Luke was a medical missionary. However, not much more evidence can be found to support that idea.
Other evidence that proves Luke wrote the book of Acts is that Acts is addressed to the same official that received the Gospel of Luke. This is found by comparing Acts 1:1 with Luke 1:3-4. Acts 1:1: "In my former book, Theophilus, I wrote about all that Jesus began to do and to teach until the day he was taken up to heaven, after giving instructions through the Holy Spirit to the apostles he had chosen." Luke 1: 3-4: " (3) Therefore, since I myself have carefully investigated everything from the beginning, it seemed good also to me to write an orderly account for you, most excellent Theophilus, (4) so that you may know the certainty of things you have been taught." Because Luke's first book was written to Theophilus as was Acts, Luke must be the author of both.
Another reason to believe that Luke is the author of Acts is the way both the book of Acts and Luke are written. The vocabulary, grammar and style are not only consistent throughout both gospels.
Luke was an eyewitness of some of the events in chapters 16-28, where he changes his 'they' statements to 'we' statements. An example of this is in Acts16:10-11, 16: " (10) And after...
