The most likely author of the Gospel of Luke, as well as the book of Acts, is the physician and companion of the apostle Paul, Luke. According to evangelical Christian belief, Luke was a Gentile and a meticulous historian who wrote his Gospel in order to provide an accurate and orderly account of the life, ministry, death, and resurrection of Jesus Christ.

In the passage Luke 1:68-70, Luke begins his Gospel with a song known as the “Benedictus” or the “Song of Zechariah.” This song is sung by Zechariah, the father of John the Baptist, and it praises God for sending a Savior and fulfilling his promises to the people of Israel. It is a proclamation of the fulfillment of God’s plan for redemption and salvation through the coming of Jesus Christ.

Evangelical Christians view the authorship of Luke as inspired by the Holy Spirit and believe that the Gospel of Luke presents a compelling and accurate account of the life and ministry of Jesus Christ. They also see the passage in Luke 1:68-70 as a powerful declaration of God’s faithfulness and fulfillment of his promises, which is a central theme throughout the entire Bible.
