If Lent is a season for acknowledging the things that draw us away from God, Advent is the season for embracing the things that turn us towards God, towards the fullness of the vision given us by the prophet Isaiah. Both of these moves are repentant, and both are difficult – but one of them invites us to focus on joy and hope which, ironically, may make it the more difficult practice to observe well as it can be replaced with false cheer and aggressive celebration.
