At one of the classes I was in last week in Frankfort, Indiana, the teacher put up a picture like this and asked us whether it was a rabbit or a duck. My first thought was duck, but I could see the rabbit too.  Through the class on the doctrine of holiness we had to refer a lot to this picture, because sometimes in issues of theology when you look at something from one side it really looks like a duck, but then when you check it out from another angle, it sure does start to look like a rabbit.
