Exploring Higher Dimensions?

When talking about God, angels, etc., you may sometimes hear it described as a "spiritual/higher dimension". In fact, authors such as Billy Graham and C. S. Lewis used just such language. It's an interesting description, but what does it mean? Are there other dimensions? Are they like the three dimensions of space we have only... more? Where did this talk come from?

Joining us today is Dr. Christopher White, an expert on the origin of and conversation around higher dimensions and their relationship to Christian faith.
