G. has posted a short allegory (I believe it is his own) for the necessity of the atonement about a lion and a robin. I really like it, and you should read it. It begins:
In the grove in the evening, the lion heard a great racket from a father Robin and his brood and went to investigate.
“Friend Robin,” the lion said, “why do you make a fuss?”
The rest is not long, and is worth your time.
