Honey, listen to me. She's found something that works for her. She's happy with it. It's not her fault. God isn't mad at you, or your sister. She's probably praying to Buddha to help your baby brother. I'm terribly sorry that your brother has cancer, but seriously- it has nothing to do with your sister's religion. I promise you, it doesn't. She's happy with who she is and what she is, so there's really nothing you can do. If she's unhappy Christian, then you're pretty damn selfish if you want her to be Christian. Same goes for your mother. Look, I'm not trying to be mean, I'm just saying, that it's not your sister's fault, god's not mad at you OR your sister, because it has nothing to do whatsoever with your brother's cancer. Cancer is a biological thing. Someone in your family probably had it. I'd pray for your brother, but I doubt you'd approve of a Pagan praying for your brother. You'd probably think it'd make it worse. I do hope that he'll get better, though. I also hope that you'll accept your sister for who she is. She's your sister. You've known her all your life. She loves you. And if you really love her, then you'll trust her. Let her be happy. I really do hope your brother gets better. It's so sad when babies get sick.
