We come once again to Advent, the beginning of the liturgical year and the great season of waiting. Christian life has a permanent Advent quality, for we are always expecting the coming of the Lord. Now, Jesus came, he will definitively come, and he is coming even now—for the risen Lord wants to take up residence in us today. So Advent is, perhaps most immediately, a preparation for that coming; we are getting ourselves ready to receive the Christ who wants, even now, to be born in us. Well, how do we do this? Our readings for this first Sunday of Advent give us some wonderful instruction.
