December 8
“The exhortation to be watchful resounds many times in the liturgy, especially in Advent, a season of preparation not only for Christmas, but also for Christ’s definitive and glorious coming at the end of time. It therefore has a distinctly eschatological meaning and invites the believer to spend every day and every moment in the presence of the One ‘who is and who was and who is come’ (Revelation 1:4), to whom the future of the world and of man belongs. This is Christian hope!”
-Pope St. John Paul II
