There are some excellent resources to help us to keep advent well appearing around the place:
The natwivity is an opportunity to follow the unfolding Christmas story on Facebook or Twitter, with real-time updates from the various characters involved.
The Christian Aid advent calendar (here) combines reflections on the Christmas story with invitations to learn more about justice issues.
The Spring Harvest advent calendar (here) is giving away a free download today; knowing the organisation, I imagine it will combine gifts like this with reflections over the period, but I’m guessing here.
If you use the YouVersion Bible app on your mobile, Tearfund have put out a good reading plan for advent here.
