I love good, expository preaching; it's the best kind of preaching by a long shot. When I'm studying a text, I love to download a sermon that a expository preacher has preached on the same text and listen to it. So when a great expositor indexes his library of sermons and makes this freely downloadable on the web, that's cause for shouting. John Piper's sermons are available at Desiring God. Danny Akin's sermons are available at SEBTS. And now John MacArthur's sermons are available at Grace to You!
