This is an interesting message about the Biblical doctrine of Hell, it's about 35 minutes long.

This talk is by Timothy Keller in his Reason for God Series of Talks

The Reason for God by Timothy Keller is in some ways an updated, contemporary “Mere Christianity”. Keller, like C. S. Lewis is dealing with some common objections to the idea of God and then also presenting a positive argument for basic Christian belief. I think he does an excellent job and I applaud him. He was also applauded at Google Headquarters just one year ago yesterday, as he presented some ideas from his book to the Google Staff. The presentation is offered here via YouTube. Seems like the turnout for Keller's talk brought an unusually large crowd of Google employees compared to the many presentations by other visiting authors. I highly recommend the book, but you might also want to watch this video presentation, followed up by interesting questions from Google folks. - Richard Dalton
