Have you ever received or opened a gift that was never for you? How did you feel when opening it? 2000 years ago, this is how many Jews felt opening the gift of Jesus, which they believe was sent erroneously.
For many the Messiah would arrive on a golden throne, but many had not understood His mission to save them from their sin. This is why in Luke we find a strong emphasis on the Great Reversal. This theme reminds us that this gift unwrapped in Bethlehem was not for the proud, or the powerful, but for the humble and hungry for righteousness. God's gift for humanity is not tagged for those that don't see a need for Him, but rather for those that realize their brokenness and hopelessness apart from Him.
