There’s a lot going on when Jesus enters Jerusalem on Palm Sunday. One of the things that amazes me is how he heads right into the belly of the beast.
In other words, whatever it was that motivated Jesus to lower himself for the incarnation and crucifixion should motivate us. So, the passion of Jesus is meant to be a model - a paradigm - for our passion. If Jesus was a passionate Messiah, we're to be passionate people. And, if we want know what that looks like we don't have to go much further beyond Bethlehem or Golgotha.
