Jesus is not an innovation or detour in the story of God’s relationship with God’s many children. This is a basic thesis of each of the Gospel writers. Here, at the close of Luke’s narrative, Jesus helps his disciples understand the Scriptures to demonstrate that the seemingly shocking and shameful crucifixion was actually central to God’s plan. God’s promises have remained in effect and are wholly irrevocable. In these verses, Jesus prepares his followers for the difficult days ahead, too incredible to believe. They would be his witnesses even in those dark days. They would be bearers of God’s precious gift in the form of the Holy Spirit.
