Before I vanish again - way too much happening around here, so much that I've lost my booked-and-paid-for Advent Quiet Day tomorrow (2 funerals) - here are a couple of online spaces for a short Advent reflection each day:

Hopeful Imagination - a group blog (may miss the odd day)

Northern Baptist College - 10-15 min liturgy.

Experience.  Enjoy.

And as I'll be there too - share!

Updated: if you want to travel through Advent with a URC minister, Craig has some reflections and links worth a look here
