It depends on how you defined "miracles" itself. For me, miracle is not only seeing lame man walk, blind can see but miracles can be happen in many ways. And yes, I personally believed in miracle. I considered a very bad person (most of the time doing bad things) completely change as miracle, people save from any calamities is a miracle. When you remember the earthquake in Haiti and the hospital broke down and there was a baby there who was alive under those hard cement, etc is a miracle for me.
