Today's passage portrays Jesus' entrance to Jerusalem, which we celebrate on Palm Sunday. John connects the recent sign (or miracle) of raising Lazarus from the dead with the crowds welcoming Jesus as their king. It seems Jesus is self-consciously fulfilling Zechariah's prophecy about the promised king by riding a colt into the city. As expected, the religious leaders, who have been worried about Jesus for some time now, are not happy with this open display of support for him as Israel's Messiah.
As usual, the disciples don't totally understand what's going on, but they will after Christ's death and resurrection. How can we get ready to welcome Jesus as our king?
