I‘ve heard of this a few times, and once was in a small town near where I live. A cop was going to work and made a different route to work this one day and found a woman pinned under her car. She had tried to get out of her car but the car had rolled and caught her under it. This was in the local paper. The cop didn‘t use the car jack to do the lift but just lifted the car enough to get her away from it. It was like a quick impulse thing, it seems where a person wants to hurry and help someone and they just somehow are able to do a supernatural thing. Only God could have allowed this to happen like this --- don‘t you think?
