The reality is that, if we figure to survive in this world, we had better have hope. The ancients knew that. Do you remember Pandora? Mythology has her as a lady endowed with every charm...the gift of all the gods. She was sent to earth with a little box which she had been forbidden to open, but curiosity finally got the better of her...she lifted the lid and out from that box escaped every conceivable kind of terror. Pandora made haste to close the box up again, but it was too late. There was only one thing left...HOPE. That was the ancients' way of saying how important hope is.
Even when all else is lost, there is still hope.
This was what had sustained the Israelite faithful from generation to generation. This was what energized the crowd along Jesus' parade route that day.
