That's not true. Any one, no matter who they are or where come from can enter into the Kingdom of Heaven (even you too) if they live chose to spend their life in a pure way, by forgiving the ones who hurt them, loving and caring for all people and choosing to be Wise and repenting for there sins, and most of all loving GOD.
It's can only be hard to do those good things if you do not let go of your sins and vices. I mean everyone, not just you.
I'm not perfect myself. I am probably a sinner I just try my best.
All you gotta do is Try Your True Best
