I've been enjoying the ezine Reformation21 so much - several months out so far. If you aren't reading Reformation 21, then do. It's a great magazine (sorry, ezine).
And then there's the blog. Mixes devastating (though always gracious) theological-cultural critique, Bible teaching, personal musings of the contributors (when they're godly men like these it's worth reading personal musings) and all with good-humoured digs at each other. Carl Trueman's neat critiques drive home with such a sense of humour that it's lightened many a day. His latest post had me in stitches. Then I realised that while he had me helplessly laughing he'd sneakily driven his point in under my defenses :o
