It would have been interesting to see this gentleman follow up his reasoning with scriptural support. He says that Christianity has learned much of it’s theology about heaven from Dante and Michelangelo, however he neglects to put much scriptural support behind his supposition that the ‘traditional’ ideas are wrong. I wouldn’t disagree that many people do have a wrong view about heaven, but I don’t agree with the things that he brought up in his interview.

Two excellent books on Theology are Basic Theology by Charles C. Ryrie and Understanding Christian Theology by Swindoll & Zuck. These books cover very difficult Theological concepts in a way that the average person will understand. Plus, they will take you to scripture so that you can check out what they are saying based on what scripture says.

Above all, beware false teachers, see I John 4:1-6 and many other scriptures.
