Can we try make some kind of special observance of this Ember Day? Here are some suggestions, they will obviously suit different life-styles. Try to pick one or two that would work for you:
Spend a little time in silence today, and open your mind to God and His work in our world..
Do some serious thinking about your spiritual life, and what you might need to confess to God.
Read your Bible, possibly Luke's Gospel, say the first Chapter.
If you are able, miss out a meal today, or determine to have a "plain day".
