Greg Sheridan AO is a noted journalist for The Australian newspaper and one of the nation’s most influential national security commentators. At this luncheon, Greg asked existential questions that are important to both Christians and non-Christians alike, including: Is God dead? Why is Christianity vital for our personal and social well-being? Why does the world need faith now more than ever? A thought-provoking afternoon filled with discussion and laughter followed, as you will see in the clips below.
