I think God gives us so many chances before our time is up, Some people have warnings I believe. I have heard tales of people seeing angels seconds before they die, simply by saying on their death bed, here are the angels they are here to get me then literally drop dead. As far as having a feeling if I get into the car and drive down the road I am going to be killed, I better stay home... no.. I seriously doubt it works like that. When your time is up, you will go, whatever you were here for is over.
