The Gospel of Luke, written by the physician Luke, is a detailed, orderly historical account of Jesus' life, focusing on His compassion, salvation for all people (especially the poor/marginalized), and fulfilling God's promise to Israel and the nations, tracing Jesus' lineage to Adam, detailing His birth, ministry, journey to Jerusalem, death, and resurrection, presenting Him as the Messiah and Savior for everyone, not just Jews. In essence, Luke presents Jesus as the compassionate Son of God, God's perfect Man, offering salvation and restoration to all people, fulfilling ancient promises in a detailed, historical account aimed at reassuring believers.
