What is grace? Do we need it, and if so, how do we get it? According to Cathleen Falsani, religion writer for the Chicago Sun-Times, grace is everywhere and available to everyone, regardless of religious affiliation or creed—yet it's a difficult concept to pin down or define in narrow terms. Dr. Oz talks with Cathleen about her quest to understand and experience the spiritual concept of grace through her encounters with people of diverse backgrounds around the world. Plus, Cathleen shares anecdotes from her book Sin Boldly: A Field Guide for Grace and talks about her own definition of grace.
