My faith says that you cannot get to heaven except through Jesus. Believing in Jesus has many definitions according to the bible. I don't know if it is all of them, or part of them that matters. I know what matters for me.
My faith also says we have no right to judge, or we shouldn't judge, unless we want to be judged in the same way. Jesus came to save, not judge.
I don't neccessarily believe your friend would go to hell, or even that you would go to heaven. I'll leave that up to God.
