JESUS led a very humble and poor life while on earth. If you think about the type of entrance a king would make into a city, you would probably imagine one that encompases a great deal of pomp & circumstance. In this dipiction, the greatest king to ever walk the earth choose to ride the back of a donkey, again reinforcing the fact that he practiced what he preached.

As I think about this event, his mother rode a donkey into Bethlemhem 30 plus years prior. I have never thought about tying these two event together prior to this point, but I'm wondering if these two events are tied together symbolizing the life of JESUS' has come full circle.
