Additional Information
This is the concluding post on this unpopular topic. While preparing for the seminar I read several older sermons on the topic of hell – all available online – just to see what they were like. There are links to these below, all of which are downloadable PDFs. Finally, the whole idea for the Saturday Seminar at Calvary Chapel Bible College Indianapolis (CCBCi) grew out of an assignment for a theolodgy class with Trinity Evangelical Divinity School (TEDS). That paper is also accessible below. Thanks for your interest!

Central Reflections 
I love the old sermons by Edwards, Spurgeon, and Wesley. Thanks for taking on such an “unpopular topic”.
And thank you for taking note of them!
