I was coming home from work yesterday,going about 45,and from out of no where,I was hit on the drivers side,my car went up,and my front wheel flew off hitting another car,and I said Jesus please help me,the front went down and the car slide sideways up and over the sidewalk and into the parking lot,a man came over and told me he was a doctor,and he couldn't believe that my car didn't flip,and that I was not hurt.Thank you Jesus.
