In "I Am Legend"... (possible spoilers)?
The virus became air borne, so that everyone who was not immune got it. So, no one could avoid it, because it was in the air -- which is everywhere. Will Smith didn't get it because he was naturally immune to it, like everybody in the village at the end. He wasn't the only one -- at one point in the movie, he gave a statistic of how many people had been infected and how many were immune. There were millions who were immune, but since they were so many less immune people, most of them were killed by the infected people. So the only remaining ones were like Will Smith and the people in the village. Because he and the lady and her son were out by themsevles, we can assume there were other people trying to survive alone. WHY he was immune is just a scientific thing. In real life, some people cannot get certain diseases, while others can. This can just be from the way they are born, or because throughout their life they were in an enviroment that make them immune. Just like some people have allergies/asthma and others don't. (-=
Will the Holy Spirit dwell in an unclean temple?
1 Corinthians Ch3:16-17Know ye not that ye are the temple of God, and that the spirit of God dwelleth in you? 17If any man defile the temple of God, him shall God destroy; for the temple of God is holy, which temple ye are.
