If you sell your soul to the devil can you ever earn it back? The better question is, HOW does one sell their soul? I remember when I was a kid maybe around 7 or 8 or so I was joking around about it saying I sold my sold, or something.. I don't EXACTLY remember but parts of me think I did, which sounds messed up but I am poorer then bricks and always have been, so could somebody just "give their soul to the devil" and not even have anything in return?

All those metal and rock bands that sold their soul, can they still repent and be saved or are they hellbound?

Thanks!
