Here are a few links that I've marked that are worth passing on:
Tim Challies wrote a superb article entitled What It Means to Be Reformed, and followed it up two days later with a fine article entitled Credo.
Mark Dever wrote a piece on questioning professions of faith. What, you mean "I prayed a prayer" isn't sufficient??
Always helpful, Milton Stanley provides a link to an article on using Scripture more in worship. Milton's site is a fine source of good writing and thinking.
My problem with things Emergent is that it seems too similar to old liberalism in new clothes. Phil Johnson has some worthwhile insights.
