[Adam the Fish]

I'm sorry you've had to deal with losing your dad - I know that it's not easy.

If you believe in Christianity, then you presumably do so on the basis of the teachings of the Bible and your interpretation of those. To my knowledge, there isn't a passage which says that, and it's certainly not a very common modern interpretation.

I personally don't believe in any god(s), though, and I think it would probably be beneficial for you to see death as a natural part of the process that actually is life. You can't have life without also having death at some point, because life is finite; there's little we can do about this except make the best of life we have whilst we have it.

Best wishes.
