Didn't have an answer for this
My 10 year old nephew asked me this question and I didn't really have an answer for it (he doesn't know I am the last person in the family to ask questions about god to) he said if we do good things we go to heaven I said yes that's right. And if we do bad things we go to hell and I said yes that's right. He then said hell is our punishment for doing bad I said yes you are correct. Then next question really threw me for a curve. He said if the devil wants us to be bad and we are bad why would he punish us for doing what he wants?
Normally I would say don't worry about it cause it isn't real, but that is not how my brother and sister in law are raising him and I am not going to get in the middle of that. I said It is a punishment because we would not be with god ( I think that's what I was told in catholic school). He then says yeah but wouldn't the devil reward us and not make it a punishment because he won (he compares everything with winning or losing)
Now at this point I was stumped and didn't know how to answer. So I said talk to your dad about this cause he knows more then I do. My brothers answer was because "hell is a punishment." So could someone please give me a better answer then "hell is a punishment" My nephew did not really like that answer and I could see my brother starting to get mad so I changed the subject to the NBA playoffs before my brother lost his cool. ANy answers would be greatly appreciated.
