Is sin allowed into heaven?

None of us know for sure, but I have theories. The meaning of life is to choose between the devil and God. People in Heaven, I think, do not sin because the devil isn't in it. He isn't there to influence us to sin at all, so therefore why would we sin? We have free will in Heaven because we CHOSE God, and by choosing Him, we get into Heaven. My family belive that you get one last chance after life to go to Heaven, and you get in by asking for forgiveness and choosing God. The only reason God made earth was so that we could CHOOSE. He doesn't want us to pick Him because He says. He wants us to choose Him because we love Him with our own free will. I hope that helps.
