 Although I am a lifelong atheist, for the first time the Bible started to make symbolic sense to me.

Having said that, and noting that his lectures are purely about the psychological rather than the theological value of the Bible, Peterson is a devout Christian. “Yes. Which is a form of insanity. The ethical burden is ridiculous. God might swipe you down even though you’re doing the right thing. But it’s your best bet. There is a great level of reality out there which we don’t know and don’t understand. We can bargain with it, but it doesn’t guarantee you anything and God can turn on you. That is the thing about life. There’s no guarantee of success.”
