How do you deal with doubt? Can we really believe in a personal God who answers prayer? How can we suggest there is a loving God when we see so much evil around us caused by both human activity and the natural world? And what about the evil done in God’s name? Should we consider creation an act of vanity? Isn’t it more noble to try and better society by forging our own moral codes, rather than relying an outdated religious text? These are some of the questions handled by Ravi Zacharias and Vince Vitale at a Q & A at Princeton University in April 2013.
