Or maybe you.
What if you get to heaven and you find out the Muslims are right, and Allah is not happy with your Islamophobia.
What if you get to heaven and find the Shintos are right, and Amaterasu is not happy with your racism against Asian people.
What if you get to heaven and find that the Hindus were right, well, you get the idea.
Frankly, I find Christian Heaven to be a bit messed up.
By Christian philosophy, Jeffrey Dahmner went to heaven and Ann Frank is burning in hell!
So let's review.
Before he died, the Milwaukee Cannibal found Jesus, was baptized in the Prison pool, and repented his sins. In Christianity, if you are sincere, that's enough to get you into heaven, all your sins are forgiven.
MEANWHILE, Ann Frank never accepted Jesus into her heart. And since your God is really, really into being worshipped the right way, she went to the same Hell as the Hindus and Muslims and Shinto who are good people but didn't worship the right God.
Now, I don't think there is anything after this, but in a just universe, Dahmner should be punished in the afterlife and Frank should be in Heaven, as she was largely innocent.
