Yesterday was one of those Sundays when I gave my homily and felt like it didn't work. It was too long and too complicated. I had two Masses in a row, so I could call the audible in between and change everything for the second version. Many times it's only in trying to preach on something that I discover the best way to try to disclose the mystery.
Yesterday, to keep things simple I came upon the metaphor of making space. In many ways I think this is a fruitful theme for Advent; during this season we try to make room for God, to 'make straight the way of the Lord.' We try to find time to pray, to be apart with the God who is so Other.
And yet, when we come near to the mystery of Lord's Nativity, we realize that our true joy is not our making of space for God in our lives, but God making space for us within the mystery of the Blessed Trinity. I think it comes across in yesterday's reading from 2nd Samuel; When David wonders if he should build a Temple for God, the Word of God comes back to him saying that it is God who will build an eternal house for David. The dynamic is repeated in the mystery of the Lord's Annunciation; Mary's fiat gives the Word of God a living and perfect tabernacle from which to born into our world, but the overwhelming good news of this is that revelation of the Son of God borrowing humanity from Mary prepares a place for our humanity within the inner life of Trinity.
Yes, like Mary we must consent to the presence of God within, and make a space for God in our lives. But so much greater than this is the space God creates for us within the veil of his own life as mysterious holiness, delight, and joy.
