One of my favorite conferences that I have attended numerous times is the Desiring God (Bethlehem) Conference for Pastors, at Bethlehem Baptist Church in Minneapolis, where John Piper pastors. I wanted to attend this year, but was not able to, but still can get in on it live through their video streaming page.
Sam Storms is the main speaker for the conference, and John Piper will be doing a biographical sketch of C.S. Lewis. You can read the speaker bios at the Desiring God website. Here is the schedule for the conference. Remember, the times are Central Time, so in California (where I live) you need to subtract two hours (opening session on Monday, Feb. 1, would begin at 5 pm Pacific Time).
