The power of The Gospel of Jesus Christ According to Luke is in its divine authorship, but that is combined with the authorship of a respected doctor and historian. Luke's sources were eyewitnesses to the events in the gospel. His "orderly account" contains historical details and precise descriptions. The order and flow of the book clarify Jesus' purpose and integrate his actions and teachings, such as his embodiment of servant leadership.

Luke, writing to the Greeks, does not assume that his audience is familiar with the Old Testament or even the land and customs of the Jews. He includes references and explanations to aid their comprehension. On the other hand, he does not avoid the Old Testament, for his goal is to "draw up an account of the things that have been fulfilled among us." He links prophecies in the Old Testament to Jesus and shows how those prophecies have been fulfilled.

Furthermore, Luke involves his readers in the life of Jesus. He shows the personalities and everyday activities of Jesus and the men and women who follow him. The readers watch the disciples struggle with Jesus' identity and find themselves asking the same questions the disciples ask, "Who is He?" Jesus' claims of divinity run counter to the naturalistic worldview of many of our readers, yet they are drawn to the One they meet in this gospel. They often come to "wish it were true," and can then do some serious thinking about the truth of Jesus' claims.
