One of my fav pastors & speakers is Mark Driscoll & he's all about Piper. They're homeboys too. He wrote a blog called "Why I Love John Piper." Pretty good read. I like it. Especially reason #4 = "By not trying to be cool... he's cool." I DEFINITELY resonate with Driscoll betting that Piper's only got 1 jacket. It's this ugly tweed blue one he wears all the time... every time he was at Passion for the last 10 years anyway.
