Luke, written somewhere between 60-80 A.D., is the third and longest of the synoptic gospels (the three that agree with each other–Matthew, Mark, and Luke). The author may have been the physician who accompanied Paul on some of his trips, so that would explain the educated language and rich vocabulary of the work. In addition, the author is acknowledged to be one of the best historians who ever wrote; his eye for details and historical accuracy are exceptional. Archeological finds over the years have proved his statements repeatedly, regarding politics, ship sailing, winds, harbors, towns, . . .
Luke had several purposes in mind when he penned this gospel. He wants to show Jesus as the Messiah, but he extends the message of hope to all the world, not just the Jews. One example of this is the new name he gives Jesus, seen nowhere else in the gospels—savior. Jesus is shown as not only the fulfillment of the Old Testament but a bridge to the new world of Gentiles. In addition, he shows Jesus with the outcasts of society such as women, children, the poor, the oppressed. Other themes involve joy, prayer, and the Holy Spirit. Luke is the warmest and most vibrant of the gospels. As you read it, remember he also wrote Acts, which should be seen as a continuation of Luke.
