John has pointed to Jesus, so Luke turns now to describe Jesus' preparation for ministry. A divine endorsement accompanies Jesus' arrival (3:21-22), while the genealogy (3:23-38) and the temptations (4:1-13) give his historical and spiritual credentials. These latter two passages highlight Jesus' connection to Adam, showing that Jesus, though unique, has come to serve all humanity. Jesus' faithfulness to his ministry, along with God's endorsement of him, is the theme of Luke's opening presentation of Jesus' ministry.
