Yes, God can, and by my personal experience having missed 4 car bombs, God can wisper and tell you to take a different route today. Though I must admit, one girl that worked at the Christian Embassy was on Bus 14 about 4 seats from the front. The suicide murderer was standing right behind her when he tripped his charge. It blew everything up right up the the back of her seat, singed her hair and she got some grit in her eye. From the back of her seat to the rear of the bus it tore seats, windows walls and roof off of the frame of the bus. Tossed the roof of the bus over a 4 story building.
That bus blew up less than a hundred yards from my wife.
The girl was basicly unharmed, everyone to the rear of her was shredded into chunks.
So, God can do as you say. But in most of the stories, including my closest call, God just gets you out of the way.
