I had considered the eventual answer to MS would be "a miracle," (I know of one woman in Texas, who formerly had MS, and considers her experience of improvement back to normal was a miracle.) but now I agree with Francis S. Collins in his book, The Language of God
In modern parlance, we have cheapened the significance of the word "miracle." We speak of "miracle drugs," "miracle diets," "Miracle on Ice," or even the "miracle Mets." But, of course, that's not the original intended meaning of the word. More accurately, a miracle is an event that appears inexplicable by the laws of nature and so is held to be supernatural in origin.
Now I realize that the processes in the human body are not completely understood (although most physicians would have you believe that they know ALL about how the body works!) When the body's "laws of nature" are better understood (including knowledge of the pancreas!), then we will have our answer.
