I saw this video of the author of The Unlikely Disciple giving a talk about his experiences at Liberty University. After watching it I think I am going to pick up his book and give it a read. He makes several points through his talk that I though were very good. One is that when groups of people from the same spectrum of belief get together, such as a group of moderate liberals or conservatives, they will end up moving towards their respective extremes. This is one of the causes of the drastic polarization we are seeing in our culture today. He also talked about how bringing in other people of differing belief that you disagree with can be a positive experience. That is actually why I started getting into religious discussions and debates online and I strongly agree with him. The video is embedded below.
