"Miracles" are facts which cannot be explained by classical physics and which, from the point of view of habitual notions of the world around us, have a "supernatural", unexplainable nature at the present time.
"Miracle" are acts of God's Laws manifested in forms and methods unusual to human perception.
"Miracle" is the manifestation of Divine Laws, impossible for man to comprehend in a materialistic, soulless way of life.
These are extraordinary actions, processes, events, not usual for man's perception, beyond his perception, which cannot be accomplished by human power or art, but only by the almighty power of God's Laws.
