It's the anniversary of the start of the reformation (so tradition has it), with the nailing of Luther's theses to the door. What to do with such a day?
1. Enjoy the grace of God in the gospel.
2. Go to Theology Network and find out, who is that Luther bloke? And while you're at it, order a copy of Mike Reeves' The Unquenchable Flame and find out how we got where we are... and enjoy the best Christian book you're likely to read this year.
