David Walker blogs well at Thinking Anglicans on Advent being a time to look forward to eternity and prepare ourselves for that.
Some tasters which struck me:
In eternity, those with whom I have fallen out now, and to whom I may have behaved uncharitably, will be closer to me than the nearest human being in this present life. The Advent call to the Churches for reconciliation is therefore not so much “unity in diversity”, as “unity in eternity”.
A worship that is anticipatory of eternity will speak powerfully to our emotions, to our intellects and to our aesthetic senses. All too often we settle for being gently entertained.
To be ready means to be prepared to wait. To wait for a God who may act sooner or later than we expect.
