There's a phrase tucked away in Psalm 146 that provides the basis for our Advent hope: God "keeps his promise for ever." Without that assurance there is no hope and no sense in Advent. Our hope is in God.
Advent is a time to recall that it is not our own unpredictable desire for God that shapes our history, but God's faithfulness. Yes, Advent is a season to make our longing conscious. But primarily it is a season to become more aware of the God who creates that longing in us.
For well over a thousand years November 1, or All Saints Day, has been marked in red on the Christian calendar. The meaning behind the celebration speaks to our time, especially when distinguishing between saints and celebrities, and remembering Karl Barth's word about reading the Bible with the daily newspaper in hand. The latter tells of celebrities, the former offers saints.
