I've seen some miracles in my life and I don't use that word lightly. I also rarely talk about them.
As C. S. Lewis noted in his book on miracles, there is no miracle so impressive or extreme that it could not - and would not - be quickly dismissed by those eager to do so. You can guess the explanations: deception, misperception, hallucination, mass hallucinations.
Those of us who have experienced them are more inclined to believe that there is far more to life than is generally acknowledged.
