The way to heaven is not through action, but inaction, goes with which philosophy/religion?

Oh boy, this will get many different responses. I, myself am an atheist. I don't believe in all that, however I know that they are many different religious and each have their own rules on what is good and bad. You could do something good but in another religion it could be consider a sin. My question would be who is in the right? Essentially this question you have to answer yourself based on your beliefs.
