Medicine doesn't know what to do nor how to act. The word, death, cannot be used. Hospice is called in. We all KNOW we are going to die. It will happen but not today.
Death always comes suddenly.
If we did believe we would die we would live differently. In other words you must learn how to die before you can live. The Bible talks about worldly people being dead while alive. Jesus calls us to die to live. He that does not prepare for death is a fool.
