Luke is the third book of the New Testament and the third Book of Gospels.
As with the other two synoptic gospels—Matthew and Mark—this book’s purpose is to reveal the Lord Jesus Christ and all He “began to do and to teach until the day he was taken up to heaven” (Acts 1:1-2). The Gospel of Luke is unique in that is a meticulous history—an “orderly account” (Luke 1:3) consistent with the Luke’s medical mind—often giving details the other accounts omit. Luke’s history of the life of the Great Physician emphasizes His ministry to—and compassion for—Gentiles, Samaritans, women, children, tax collectors, sinners, and others regarded as outcasts in Israel.
Called the most beautiful book ever written, the Gospel of Luke begins by telling us about Jesus’ parents; the birth of His cousin, John the Baptist; Mary and Joseph’s journey to Bethlehem, where Jesus is born in a manger; and the genealogy of Christ through Mary. Jesus’ public ministry reveals His perfect compassion and forgiveness through the stories of the prodigal son, the rich man and Lazarus, and the Good Samaritan. While many believe in this unprejudiced love that surpasses all human limits, many others—especially the religious leaders—challenge and oppose the claims of Jesus. Christ’s followers are encouraged to count the cost of discipleship, while His enemies seek His death on the cross. Finally, Jesus is betrayed, tried, sentenced and crucified. But the grave cannot hold Him! His Resurrection assures the continuation of His ministry of seeking and saving the lost.
