“[Grace is] my favorite word in the lexicon of the English language.  It’s a word I’m depending on.  The universe operates by Karma, we all know that.  For every action there’s an equal and opposite reaction.  There is some atonement built in: an eye for an eye, a tooth for a tooth.  Then enters Grace and turns that upside down.  I love it.  I’m not talking about people being graceful in their actions but just covering over the cracks.  Christ’s ministry really was a lot to do with pointing out how everybody is a screw-up in some shape or form, there’s no way around it.  But then He was to say, well, I am going to deal with those sins for you.  I will take on Myself all the consequences of sin.  Even if you’re not religious, I think you’d accept that there are consequences to all the mistakes we make.  And so Grace enters the picture to say, I’ll take the blame, I’ll carry the cross.  It is a powerful idea.  Grace interrupting Karma.”
