The Gospels are not strictly biographical or chronological accounts of Jesus' life. They portray Jesus' identity and mission through carefully selected stories arranged by the Gospel authors to convey theological messages and elicit a response of faith from readers. While the Gospels differ on some details like the timing of Jesus' crucifixion, their primary purpose is to show that Jesus is the Messiah and Son of God, and to communicate the "good news" of God's kingdom through his life and teachings.
