When our introit today says “Let no one who waits on you be ashamed” we don’t mean that we are waiting for the baby born in Bethlehem. When we pray “stir up your power, O Lord, and come,” we don’t mean that we are like the Old Testament prophets waiting for a Messiah who will save us, not yet fully seeing Him. When we sing today at the Lord’s Supper, “Hosanna! Blessed is He who comes in the name of the Lord!” we are not just pretending to be those people in Jerusalem welcoming our Lord sitting on a donkey.
