As Jesus entered Jerusalem on that first Palm Sunday, the crowds gathered to worship Him, shouting 'Hosanna' and laying down palm branches and their coats on the road in front of Him to make a way for their Messiah. This crowd knew they weren't here to watch a show, but a real demonstration of authority and power. Jesus will still be a king without our worship, but He won't be our king. In worship, we declare to Jesus and to others that He is indeed in our king, and in worship, we are participants in the coming of the Kingdom of God.
