Meet Theophilus.  He's the fellow Luke dedicated his 2-volume work to (think Luke - Acts).  Much of what had happened since Jesus came must've seemed odd - a royal birth with little fanfare, a Jewish messiah that hardly anyone in the know recognized, an unexpected resurrection and hasty return to heaven, and a promised kingdom that failed to appear.  Hmmm.  Luke writes to show his friend that what's happened is actually a precise fulfillment of God's wise Plan.  He could bank on it!  What is ti about the coming and life of Jesus that seems quirky to you?
