Every year Steve Levy's congregation ask him to preach his hell sermon. They invite their friends and people become Christians. It's phenomenal preaching and if you ask me it's exactly the way to speak of judgement.
Hell is already on us. We experience it (John 3:18,36; Romans 1:18). We see the "trailers" for the main feature and everything screams at us "You do not want to go there!" Jesus does not come into the world to save some and damn others. He comes into a condemned world only to save. We are not at a cross-roads with heaven or hell in the power of our choosing. Hell is on us. Our only response is to turn to the Saviour.
Also check out the rest of the Mount Pleasant sermons. Wonderful stuff - including some recent Blackham sermons too.
