Assuming you're correct, and once you get in you stay in, then I'll agree. However, according to most Christian faiths, you also can't do wrong in heaven. For argument's sake, if Lucifer can do wrong in heaven (something that you supposedly can't do) and got kicked out (something that you supposedly can't do), hypothetically couldn't one also get kicked out of heaven for doing something wrong? I've never been there, I don't know the rules. Is it that people can't get kicked out, or that they don't? And I don't trust the "angels are different" argument. "Praise ye Him, all His angels: praise ye Him, all His hosts... for He spoke and they were made. He commanded and they were created." Angels are different, but I'm not sure if they have different rules.
