You see, at the center of all religions is the idea of Karma. You know, what you put out comes back to you: an eye for an eye, a tooth for a tooth, or in physics—in physical laws—every action is met by an equal or an opposite one. It's clear to me that Karma is at the very heart of the universe. I'm absolutely sure of it. And yet, along comes this idea called Grace to upend all that "as you reap, so you will sow" stuff. Grace defies reason and logic. Love interrupts, if you like, the consequences of your actions, which in my case is very good news indeed, because I've done a lot of stupid stuff.
