the basis of the book is that we are unfulfilled because we've grown too sophisticated for god, we're lonely, we're morally confused, and i think god is the answer for this, it fashions, religion fashions the kind of community in which you're redeemed from loneliness, it gives you the sense that when you come close to the end of your life you don't have to panic that you have wasted your life because religion can show you that you have made a difference to the world.
