As co-anchor of The Today Show on NBC, Savannah Guthrie asks the big questions. But the last month, she has been on the receiving end of some pretty big questions about a very personal topic. Savannah recently released a book called "Mostly What God Does..." It's an honest exploration of faith in real life and real time. Host Brooke Walker had the privilege of sitting down with Savannah at her own church in New York City to talk about how God's love has changed her, and how she believes God's love can change the world.
