I've had my experiences with what seemed to be miracles as well.
My blue eyes are ultrasensitive to bright light, and when I was 19, my sunglasses broke. I prayed for new sunglasses. The next day, I found 4 of them. I kept the one that best fit my needs, and gave the other 3 to some homeless people I knew.
When I lived out in the California mountains, my only transportation was a Honda CB750 motorcycle. I found out it's top speed was 125. My ex's bike could do 165. The roads to Placerville had a cliff up one side, and down the other, with sharp turns. Nothing stopped me from being stupid, but something stopped me from crashing or flying into trees (depending on which way I might have made an error).
While living in the mountains, I would regularly walk a trail to the top of the mountain I lived on. One day, I met a rather large brown bear (grizzly?). It stood up and roared at me. I listened to a little voice that told me "what would a mountain lion do?". So, I screamed at the bear, with the same sound as a ticked off mountain lion. At that point, the bear veered left, and ran full speed uphill, leaving traces of hair in tree bark.
I have no doubt about the existence of God.
