“Why do John’s disciples and the disciples of the Pharisees fast, but your disciples do not fast?” And Jesus said to them, “While the bridegroom is with them, the attendants of the bridegroom cannot fast, can they? So long as they have the bridegroom with them, they cannot fast. But the days will come when the bridegroom is taken away from them, and then they will fast in that day.”
-Mark 2: 18 – 20-

The entrance into Jerusalem is a bridal procession. Jesus is the Bridegroom. We are the Bride.
