Psalm 80:1-7, 17-19
1 Corinthians 1:3-9
Advent begins with a dawning awareness of the difficulty facing a new creation to be born in the midst of a new creation. We will need to look at some most difficult realities and still proceed even in the midst of horror at ourselves and others and the world at large.
The Chronicles of Thomas Covenant by Steven Donaldson would be an excellent series of speculative fiction to read to get a feel for Advent.
