If you have the time and you're looking for something really good to chew on, check out the videos from the recent Gospel Coalition Conference, which was held in Chicago April 21-23.
Featured speakers were, among others, Tim Keller, John Piper, Mark Driscoll, Josh Harris, C.J. Mahaney and D.A. Carson. I watched Session 1 this morning... a message by Tim Keller on discerning, exposing and destroying personal, religious and cultural idols... very eye-opening, thought-provoking and challenging.
I was planning to go to the conference but ended up not being able to... I'm so glad for the technology that allows such wide access to these sorts of events.
