Original sin is an easy one, Jim. We are all miserable, guilty wretches because a woman who never existed bit into an apple belonging to someone else who never existed. This was passed down to us in a story told by a liar. Now the only way out of our guilty wretchedness is to turn our faces to "The Lord" and, grovelling before him ("Lord, I am not worthy...") ask his forgiveness for something we did not do and which never happened in the first place. Even the tiniest of new babies are besmirched with this guilt! But, even having signed up to his club (which I'm certain he would have hated) you might well be waiting around, even long after you're dead, for "judgement day" to find out whether you've done enough to get yourself off the hook. Hope this helps!
