not that great of a god if he/she only answers SOME prayers
God cant do everything for you he can guide you in the right path. YOU as a person must make the effort, something you want in life, you pray to him an ask him for help an guidance. its your job to make the effort an do the hard work to become successful.
As far as being sick, it depends on the life style that person lives. God may need you with him in heaven, your time on earth is coming to an end. "As the story goes the good people die young an early".
A person that lived worldly lives a fast life didnt abide by god's rule an law never gave an effort an read gods word. that person became sick, God is not gonna save em.
