Roger Olson:

Much of the blame for the rise of the “new Calvinism” is ours—Arminians. We have failed to provide our young people with our theology. So naturally they think Calvinism is the only biblical, evangelical theology when they encounter it preached and taught by attractive, persuasive, young men like Matt Chandler, Mark Driscoll, Louis Giglio, et al. And when they fall under the spell of John Piper who is simply a magician at persuasion.
