Rick Warren, author of The Purpose Driven Life and pastor at Saddleback Church, is not a guy who resonates in Reformed circles. So, the word that’s been leaking out the last week or so that John Piper had invited him to be the keynote speaker at this year’s Desiring God National Conference has caused quite a buzz. Ben Terry has the audio (also below) of Piper talking to a group at Mt. Sinai Missionary Baptist Church about what he likes (and what puzzles and confounds him) about Warren.

More will probably come from this as Piper will host a Q&A live tonight at the Desiring God site.
